A New Rhinoceros From The Nebraska Miocene, Lloyd G. Tanner

Bulletin of the University of Nebraska State Museum (1924–2023)

A new species of rhinoceros, Menoceras marslandensis, is here proposed. It is based upon a nearly complete skull from the upper part of the Marsland Formation, Hemingford Group (Miocene), of Box Butte County, Nebraska. The new species was probably derived from Menoceras arikarense (Barbour), collected from the Agate Springs Quarries (Arikaree Group, Harrison Formation) of Sioux County, Nebraska, with which both Diceratherium niobrarensis Peterson and D. cooki Peterson are likely synonymous. From Menoceras arikarense, the presumed ancestral stock, Menoceras marslandensis differs in possessing the following characters: (1) very long, fused but slightly cleft, nasals, with flattened, rugose areas …

Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE Western Australian soils are low in phosphorus, frequent applications of superphosphate are required for both crop and pasture production. The recommended rates are determined from the results of field experiments that test different quantities of super and measure the extra yield.

This article discusses the recommended rates of superphosphate in relation to soil type and superphosphate history. Methods of application and time of topdressing are also discussed.

West Midlands Development : Cereals For The West Midlands, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE sandplain soils and climate of the West Midlands area are primarily suited to grazing.

However, the place of cereals is receiving a great deal of attention in view of their advantages in the early stages of development, and the need for the diversification of farm production.

West Midlands Development : Fertilizers For The West Midlands, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

FARMING the light lands of the West Midland area would be impossible without fertilisers.

Most light land areas are inherently very low in phosphate and also require nitrogen.

The nitrogen can come from fertiliser for cereal crops, or can be built up by growing appropriate legume pasture plants such as clovers and lupins.

Procedure And Structure For An Instructional Laboratory Which Supplements Research, R. S. Adams Jr.

Journal of the Minnesota Academy of Science

This paper describes the organization of a laboratory course in Soil Chemical Analysis. Students select and pursue small research problems to gain experience in the soil analyses that are discussed in lecture and required in the laboratory. Involvement of the class in an actual research problem proved challenging to both the instructor and the class. The data obtained often supplemented current departmental research. Individual projects were found to be easier to supervise than team problems. This paper reports results of a team project examining parameters of a pot experiment. Shape of the pot, methods of watering, methods of fertilizing, and …

Algal Growth Experiments In The Baradla Cave At Aggtelek (Biospeleologica Hungarica Xxi), Erzsebet Kol

International Journal of Speleology

The author kept 108 algal strains (Cyanophyta 53, Chlorophyta 35, Chrysophyta 20), of axenic cultures from the Kol-Algotheca in the Botanical Division of the Hungarian National Sciences Museum in the Baradla Cave, at Aggletek (Hungary) in darkness for 204-420 days under different environmental conditions. The experiments have proven that several algal strains can tolerate well the complete absence of light. Furthermore, that some algal strains show intensive development even under such conditions. These axenic cultures kept in the cave in metal boxes on inorganic medium have shown that the energy source used by these green coloured algae is not …

The Course Or Behavior Of Applied Zinc To Soil Containing Different Levels Of Freshly Applied Organic Matter, Artnel Samuel Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil organic matter consists of a heterogenous mixture of plant, animal, and microbial material in various stages of decomposition. It possesses characteristics which at present are not very well known. Careful studies have been directed towards the behavior of organic matter as it affects plants directly and man indirectly. Consequently, much tire is devoted to its study from the point of metal inactivation and chelation, the earlier investigations failed to produce results worthy of the efforts expended, so a loss of interest in the continued pursuit of knowledge resulted, about two decades ago when it was learned that many polyvalent …

The Influence Of Organic Matter And Ph On Transformations Of Nitrites To Elemental Nitrogen, Mohammad A. Rashid

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen occupies an important and prominent place in plant and animal nutrition. Large quantities are required by plants and must be available in the soil. Recently the use of nitrogenous fertilizers has increased manyfold. In view of the importance of this element in crop production, even greater use is anticipated in the coming years. In order to make full use of the applied nitrogen, continued investigations of soil-nitrogen relationship are imperative; however, this element presents many complex and challenging problems to investigators.

Movement Of Phosphorus In Soils As Influenced By Chelates And Soil Types, Abd-Elmonem Sayed-Ahmad Mostafa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The problems of phosphate fertilization have attracted the attention of agronomists, nutritionists, and other biological scientists due to the importance of phosphorus in animal and plant nutrition. However, the fundamental behavior of phosphorus in soil systems is not well understood. Because of its far-reaching effects, a solution of a portion of this problem is of importance.

A Preliminary Study On The Effects Of Organic Pollution Of Banners Corner Cave, Virginia, John R. Holsinger

International Journal of Speleology

Four pools were observed in Banners Corner Cave, Russell County, Virginia, over a 28 month period from November 1961 to February 1964. Three of these pools were visibly polluted with sewage which had seeped into the cave from septic tanks located on the hill above. All four of these pools, at one time or another during the study, contained large populations of planarians, Phagocata subterranea Hyman and isopods, Asellus recurvatus Steeves. Physicochemical and microbiological analyses of the pool waters indicated that oxygen tension is a low as 2.8 mg./l. in one pool and that coliforms and other forms of bacteria …

Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu

International Journal of Speleology

Experiments were designed to test the ability of the aphotic speleoenvironment to support algal growth. The first series contained gelatin cultures of Scenedesmus placed in the cave at different localities in order to establish whether or not the microhabitats have any particular effect on the multiplication of the algae. No differences were found in the cultures after a three month incubation period in the cave, which could be traced to influences of microenvironmental conditions. Chlorella cultures in sterile Knop’s solution showed measurable growth in the cave whereas if the cultures were installed into sterilized cave water or were shielded by …

DURING the summer months, leaves of many plants develop browning and scorching which progresses inwards from the leaf margin or downwards from the leaf tip.

The affected parts become dry and brittle and may break away from the remaining green areas.

Cenozoic And Recent Lunulitiform Bryozoans Of The Gulf And Atlantic Coasts, Ronald Greeley

Doctoral Dissertations

"Free, cup-shaped colonies of cheilostomatous bryozoans, equipped with vibracula, are termed lunulitiform bryozoans. This group is found in sandy and calcareous Cenozoic deposits of the Gulf and Atlantic Coastal Plains. Cupuliform bryozoans are taxonomically distinct from, but in many ways similar to, lunulitiform bryozoans; the two groups are frequently found together.

Known lunulitiform genera of the Gulf and Atlantic Coastal Plains are diagnosed and their species described: Lunulites Lamarck, fifteen species, one new; Oligotresium Gabb and Horn, six species, two new; Discoporella d'Orbigny, two species; Cupuladria Canu and Bassler, two species; Selenaria Busk, one species; Otionella Canu and Bassler, four …

Preliminary Note On The Algae Of Crystal Cave, Kentucky, J. P. Nagy

International Journal of Speleology

Collections of a preliminary type carried out in Crystal Cave, Kentucky, resulted in the identification of seven algal taxa. A Chamaesiphon (Dermocarpales) and an Asterocytis (Bangioidea) are reported for the first time from a speleo-environment. As no correlation could be found among the algae occurring in Crystal Cave and those of nearby Mammoth Cave the conclusion is reached that the cave algal floras do not originate from the algal vegetation of the surface but may have gotten into the caves at the time of the latter’s formation.

Algological Investigations In Mammoth Cave, Kentucky, H. J. Jones

International Journal of Speleology

Algological investigations carried out in the Mammoth Cave, Kentucky, revealed the presence of twenty-seven taxa representing all divisions of the Algae except the Pyrrhophyta and Phaeophyta; diatoms although observed in the samples were not dealt with in the present paper. One species, Oscillitoria clausiana spec. nov. and a form Lyngbya pusilla fa. tenuior fa. nov., both belonging to the Cyanophyta are new to science. In addition, several other rare and interesting algae were found. A comparison is made between the algal flora of the Mammoth Cave and algae found in several European caves. The ecology of the cavernicole algae is …

Diatoms From Mammoth Cave, Kentucky, Sam L. Van Landingham

International Journal of Speleology

Samples collected in Mammoth Cave, Kentucky, revealed the presence of a diversified but not too abundant diatom community in the cave. As the material was not subjected to culturing experiments but was investigated immediately after arrival, both in native and permanent preparations, it was possible to: 1. ascertain that the majority of the diatoms contained well developed, apparently healthy and functioning chloroplasts and 2. to get a rough estimate of the actual number of specimens present in a microhabitat. The identifications resulted in the recognition of 16 diatom taxa of which possibly 4 are new to science. Further studies are, …

The Effect Of Chelates On Phosphorus Availability And Mobility, Salah Ahmed Tahoun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil-phosphorus relations and plant-phosphorus relations have attracted the interest of many investigators since Liebig introduced his famous theory about the importance of the mineral matters to the plant in 1840. It was soon realized that phosphorus nutrition was a problem not easily solved for two reasons. 1. The added phosphorus fertilizers, soon after soil application are converted by some reactions in the soil to complex compounds far less soluble, consequently less available to the plant. Conclusions about this process led to controversial debates until it was discovered that a general statement covering all soils was impossible since the reactions involved …

Influence Of Compaction And Freezing On The Structure And Permeability Of Some Selected Horizons From Northern Utah Soils, Samir Ramzy Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Frequently, in evaluating plant deficiencies, one considers only those soil factors which are associated with the fertility of the soil-- mainly the levels of phosphorus, potash, nitrogen, and organic matter. A certain level of nutrition is essential for plant growth, but in order for the nutrients to exert their maximum influence on the productivity of the soil, it is equally important that a good soil environment be provided and maintained. A good environment requires that good physical conditions of soil, sir, and water be in balance.

Correcting Cobalt Deficiency, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.
