Litter Decomposition And Nutrients Release During Decomposition In A Humid Grassland Of Northeastern India, P S. Yadava, N S. Thoudam
IGC Proceedings (1997-2023)
The litter decomposition and nutrient release of two dominant grass species Sporobolus indicus (L) R. Br., Leersia Hexandra SW. and mixed grasses was studies by litter bag technique in the humid grassland ecosystem at Imphal, Northeastern India. On ermination of experiment after 12 months, the shoots decomposed from 97.2 to 100% and the roots from 82.9 to 91.8% of different species. The rate of litter decomposition of shoots were higher than roots. The decomposition constant (K) also varied from species to species. It is positively correlated with soil moisture content during the study period. The initial nitrogen, lignin and lignin …

Groundwater Concentrations Of Non-Nitrogen Nutrients Under A Medium Fertility Pasture System, L B. Owens, R W. Van Keuren, W M. Edwards
IGC Proceedings (1997-2023)
The purpose of this multi-year study was to determine concentrations and transport of non-nitrogen nutrients in groundwater under a medium fertility pasture system. Rotationally grazed grass pastures received 56 kg N/ha annually as NH4NO3 for a 5-yr period. A topsoil pH of 6.0 and available P and K levels of 28 and 168 kg/ha, respectively, were maintained. Concentrations of P, K, Na, Ca, Mg, and Cl were measured in water from springs draining each paddock. Nutrient concentrations did not vary greatly on a monthly basis but there some increases during the second 5-yr period when annual N fertilizer rates were …

Grass hay was baled with a variety of balers and tying materials in June, 1994 and 1995, at Jackson, Ohio. The bales were prepared and stored several ways. Waste hay accounted for less than ten percent of the dry matter after storage for six and eighteen months in all cases except one (a plastic wrap system intended for use with haylage). Bales stored inside had no waste. The best outdoor storage system, with less than one percent waste, used a ‘bale bonnet’ (top half covered with a plastic sheet) with the bale on a slatted pallet. One group of bales …
