Animal Production From Tropical Pastures Renovated By Subsoiling And Fertilization In The Cerrados Of Brazil, Valéria P. B. Euclides, Manuel C. M. Macedo, M. P. Oliveira
Animal Production From Tropical Pastures Renovated By Subsoiling And Fertilization In The Cerrados Of Brazil, Valéria P. B. Euclides, Manuel C. M. Macedo, M. P. Oliveira
IGC Proceedings (1993-2023)
A grazing trial was conducted, to study the effects of fertilization on the maintenance of the productivity of four tropical grasses. The paddocks were subsoiled, and dived into halves: one (LF1) received 400 kg/ha of a fertilizer formula 0-20-20.and the other (LF2) 800 kg/ha of the same fertilizers, in January 1995. Annually, 50 kg/ha of N was applied. The productivity on LF2 pastures was greater than that on FL1 pastures, averaging 520 and 410 kg of liveweight gain/ha/year. A double strategy should be followed to sustain animal production in the savanna: maintain soil P over a critical value of 3.0 …
Alfalfa Response To Varying Rates Of Phosphorus And Potassium Fertilization On Deep, Red, Limestone - Derived Soils Of The Pennyroyal Area In Kentucky, H. C. Vaught, Kenneth L. Wells, K. L. Driskill
Alfalfa Response To Varying Rates Of Phosphorus And Potassium Fertilization On Deep, Red, Limestone - Derived Soils Of The Pennyroyal Area In Kentucky, H. C. Vaught, Kenneth L. Wells, K. L. Driskill
Agronomy Notes
The Western Pennyroyal area of Kentucky consists largely of deep, well-drained limestone-derived soils occurring on an undulating to rolling landscape. A thin loess mantle overlies the limestone residuum in many areas. Soils on these landscapes are capable of good crop production, providing the basis of the rather intensive grain-hay- tobacco-livestock farming systems common to the Pennyroyal area. Because of the well-suited physical characteristics of these soils, alfalfa is a very important hay crop to this area.
Irrigating Corn On Well-Drained, Limestone-Derived Soils, John L. Ragland, J. C. Redman
Irrigating Corn On Well-Drained, Limestone-Derived Soils, John L. Ragland, J. C. Redman
Agronomy Notes
In trying to determine if it would pay Kentucky farmers to irrigate corn, one of the most important steps is to ascertain the long-time average yield increases to be expected from supplemental irrigation. The yield data reported below are the results of an experiment applicable for a fairly large group of soils occurring in Kentucky.
Apply Fertilizer And Limestone This Fall, George D. Corder
Apply Fertilizer And Limestone This Fall, George D. Corder
Agronomy Notes
As farmers push towards more economical crop production, fertilizer and limestone use will increase. If Kentucky farmers continue to help feed the world, the rate of increase will accelerate during the next decade .
Finely Ground Agricultural Limestone Is Available, George D. Corder
Finely Ground Agricultural Limestone Is Available, George D. Corder
Agronomy Notes
Kentucky farmers can purchase a more finely ground limestone than they could 1 year ago.
The Department of Agronomy, Agricultural Experiment Station, University of Kentucky, recommends that agricultural limestone be ground fine enough that at least 45 percent will pass through a 50-mesh screen. This is equivalent to the old recommendation that at least 40 percent pass through a 60-mesh screen.
What Is Good Agricultural Limestone?, George D. Corder
What Is Good Agricultural Limestone?, George D. Corder
Agronomy Notes
During the 10-year period, 1955- 64, Kentucky farmers used more than 14 million tons of agricultural limestone. The investment in the limestone plus hauling and spreading was in the neighborhood of $45 million. In 1964 alone. Kentucky farmers invested about $7 million in about 2 million tons of limestone.
Agricultural Limestone In Kentucky, George D. Corder
Agricultural Limestone In Kentucky, George D. Corder
Agronomy Notes
Kentucky farmers invested about $6 million in agricultural limestone in 1964. However, much more lime than this should have been used if farmers get the most economical crop production and the most efficient use of fertilizers that are applied or the fertility that is already in the soil.
Different Soils Need Different Amounts Of Limestone, George D. Corder
Different Soils Need Different Amounts Of Limestone, George D. Corder
Agronomy Notes
Two different soil types may show the same acidity levels by soil test but they may need different amounts of limestone to obtain the same reduction in soil acidity.

Agronomy Notes
This fall is an ideal time to apply needed agricultural limestone. Spreading equipment can get over the dry ground with less soil compaction, and limestone applied now can correct soil acidity during the winter months.
