Effects Of Char On Nitrogen Management In Agricultural Soils Of Semi-Arid Western Nebraska, Dinesh Panday

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Soils in western Nebraska are characterized by low soil organic C due to semi-arid environment in the region and further aggravated by disruption of soil aggregates and rapid C decomposition from intensive tillage, erosion, and frequent droughts. Proper management of soil C may improve soil properties, reduce N losses, and subsequently improve crop yields in this low C soil and low moisture condition. This dissertation focuses on C-rich coal char (henceforth “char”) as a potential strategy to overcome the existing problem of low C in semi-arid region. Char is an industrial by-product, resulting from inefficient coal burning during sugar beet …

The Significance Of Nomadic Pastoralism For Sustaining Soil Fertility In Northern Karnataka, India, Athani B., Gopikrishna, N. Kuruba

IGC Proceedings (1997-2023)

Pastoralist groups in India, including the Raika of Rajasthan, Pullikulum cattle breeders in Tamil Nadu, and groups such as the Dhangar, Kuruba and Kuruma of the Deccan Plateau realize a major proportion of their income from penning their herds and flocks on farmers’ fields. Focusing on shepherds from Northern Karnataka, this paper makes a first attempt at calculating the impact of penning on livelihoods, soil fertility and the national economy.

Competition Between Lolium Perenne L. And Agrostis Capillaris L. Growing Under Different Light Regimes As Response To Fertiliser Addition In A Degraded Pasture, Paulina Flores, Ignacio F. López, Peter D. Kemp, José Dörner

IGC Proceedings (1997-2023)

At the field level plants can experience solar irradiance fluctuations caused by cloud cover or canopy shading. The majority of the research in this area has been done on forestry/pastoral systems using artificial structures so that the pasture has the desired light level (Peri et al. 2006). However, the effect of a change from high to low irradiance on the seasonal plant growth and production in a degraded pastoral system has not been previously studied, especially when fluctuating light regimes are involved. The aims of this study were to evaluate tillering dynamics of Lolium perenne L. (Lp) and Agrostis …

Soil Fertility Under Grassland Compared To Other Land Uses In Acid Soil Of Himachal Pradesh, India, Sharmistha Pal, Pankaj Panwar, D. R. Bhardwaj

IGC Proceedings (1997-2023)

In the last decades severe changes in land use occurred in tropical countries, due to increasing population and their demand for food resources. Forest land is rapidly converted into agriculture or pastureland which may cause significant changes in soil fertility. Land-use exerts significant effect on nutrient availability and may also influence secondary succession and biomass production (Lu et al., 2002). Nutrient cycling in agroforestry is in between natural forest ecosystems of the tropics and most of the agricultural systems with are ‘‘leaky’’ having higher nutrient losses. Research indicated that decline of soil organic matter may occur due to conversion …

Effect Of Grazing On Soil Fertility And Trace Elements Of Temperate Desert Steppe In Northwestern China, T. Jiao, J. P. Wu, W. X. Cao, J. Qi, S. G. Zhao

IGC Proceedings (1997-2023)

Grazing is the dominant land use of temperate desert steppe in northwestern China. It is well established that the grazing process has impacts on plant production and biodiversity (Li 1997), but less is known about the effects of grazing chemical characteristics of grassland soils. Livestock feeding activities, especially the provision of supplementary sources, may influence pasture nutrient cycle, and in turn change the chemical composition of the grassland soil (Rong et al. 2001). Soil fertility may be affected by the type use and grazing intensities because these may cause alterations in soil physical and chemical properties as well as …

A Study Of Olive Mill Wastewaters Obtained From Different Treatment Processes Effects Onchemical And Microbial Properties Of A Typic Xerofluvent Soil And Wheat Yield, Nur Okur, Hüseyi̇n Hüsnü Kayikçioğlu, İhsan Bülent Okur, Bülent Yağmur, Deli̇a Teresa Sponza, Recep Serdar Kara

Turkish Journal of Agriculture and Forestry

This study was carried out to investigate the potential for the usability of treated olive mill wastewater (OMW) as an organic amendment in agricultural soils under Mediterranean climate conditions. OMW was treated by two different treatment processes as economical (E-OMW) and advanced (A-OMW). The treated OMWs and raw OMW (R-OMW) were applied to a loamy soil at a rate of 100 m3 ha-1 year-1 for 2 years. Soils were sampled 15 days and about 5 months (at harvest) after OMW application for chemical and microbial analyses in each year. The total concentrations of N, P, Cu, Zn, and phenol of …

Lithological Constraints On Resource Economies Shape The Mycorrhizal Composition Of A Bornean Rain Forest, Monique Weemstra, Kabir G. Peay, Stuart J. Davies, Mohizah Mohamad, Akira Itoh, Sylvester Tan, Sabrina E. Russo

School of Biological Sciences: Faculty Publications

• Arbuscular mycorrhizal fungi (AMF) and ectomycorrhizal fungi (EMF) produce contrasting plant–soil feedbacks, but how these feedbacks are constrained by lithology is poorly understood.

• We investigated the hypothesis that lithological drivers of soil fertility filter plant resource economic strategies in ways that influence the relative fitness of trees with AMF or EMF symbioses in a Bornean rain forest containing species with both mycorrhizal strategies.

• Using forest inventory data on 1245 tree species, we found that although AMF-hosting trees had greater relative dominance on all soil types, with declining lithological soil fertility EMF-hosting trees became more dominant. Data on …

Burning With Potential: Understanding The Relationship Between Biochar And Agriculture Of The Northern Glaciated Plains Ecoregion, Kaitlyn Abrahamson

Electronic Theses and Dissertations

Achieving global sustainable agriculture is one of the most incredible challenges of this century, yet many continue to try to solve this problem through the development of precision technologies. Biotechnologies, such as biochar, can perform like a precision technology while protecting agricultural land from soil erosion and fertility loss. The Northern Glaciated Plains ecoregion of the United States is little researched in the benefits from the use of biochar through improved soil nutrient capture and water retention, crop health improvements, and yield increases. The study plot has four sections of corn stover biochar and eight sections of control sections. This …

Soil Phosphorus Fractions After Long-Term Fertilizer Placement In Different Kansas Soils, M. J. Coelho, D. A. Ruiz Diaz

Kansas Agricultural Experiment Station Research Reports

Phosphorus (P) fertilizer placement can affect the long-term dynamics and forms of P, and the overall soil P pools. These changes can vary by soil type, and affect P uptake and use efficiency by crops. The objective of this study was to evaluate the changes in the labile P fractions in three Kansas soil types under P fertilizer placements (broadcast versus deep band) after ten years of crop rotation. Three field studies were conducted at Scandia, Ottawa, and Manhattan. Three treatments were evaluated: 1) a control with no P fertilizer application and two fertilizer treatments (80 lb P₂O …
