Twenty-five years of phosphate and potassium fertilization of a crop rotation

Barber, Stanley

2005 Nutrient Cycling in Agroecosystems

doi:10.1007/BF01073562

Effects of rate and placement of phosphate and potassium fertilizers was studied using a 4-year rotation of corn (Zea mays L.), soybeans (Glycine max L.), wheat (Triticum vulgare L.) and hay (later changed to corn). Yields increased with increased P until 22 kg P ha−1 yr−1 was applied. Yields...

2005 Nutrient Cycling in Agroecosystems

doi:10.1007/BF01073563

Two phosphate rocks, one from Pesca (Colombia) and the other from Togo, were acidulated to various degrees with H2SO4 and H3PO4 for evaluation in varying granule size ranges. Products acidulated with H2SO4 were also prepared using different drying temperatures. Phosphorus availability was...

Changes in quantity of mineral nitrogen in three grassland soils as affected by intensity of nitrogen fertilization

Prins, W.

2005 Nutrient Cycling in Agroecosystems

doi:10.1007/BF01073564

Changes in quantity of soil mineral nitrogen down to a depth of 1 m in cloverfree grassland were monitored within one growing season and over successive growing seasons. Accumulation of mineral nitrogen in the soil occurred on permanent grassland with split application of nitrogen totalling more...
