Manure injection is an alternative manure application method that can alter the spatial distribution of relative to surface application. Eight study sites were established assess how versus broadcasting affects corn (<i>Zea mays</i> L.) silage growth, soil nutrient dynamics, and distribution. Specifically, yield, nitrogen (N) uptake, nitrate (NO<sub>3</sub>-N), carbon mineralization (C-min), permanganate oxidizable (POXC) measured. Soil samples taken represent whole plot means for both...
Abstract Manure injection alters the spatial distribution of manure by concentrating it in a subsurface band which can lead to differential soil nutrient and growth small grains. This study assessed effects fall applications on NO 3 ‐N, active carbon, grain compared broadcasting no control. Soil samples were taken represent whole plot means for all treatments, while in‐band (IB) between‐band (BB) injected plots assess after injection. Small forage also IB BB growth. analyzed permanganate...
Abstract Producers utilizing fall manure injection have reported increased growth and greenness in small grains growing on the band compared to between bands. To determine how producers should manage potential differential growth, 24 sites under were established. Soil samples taken in‐band between‐band 1 month after application at silage harvest for soil NO 3 ‐N. Small grain stage was assessed planting harvest, while dry matter (DM) yield forage nutritive value parameters harvest. ‐N...
In order to identify new ways mitigate methane emissions from ruminants, six medicinal plants, Achyranthes aspera, Azadirachta indica, Andrographis paniculata, Helicteres isora, Tinospora cordifolia and Piper longum, were evaluated in vitro with respect ruminal fermentation methanogenesis. A three-stage approach n = 6 per treatment was applied. Two 24-h Hohenheim gas test experiments performed by incubating the plants first as sole substrate then added a basal diet (10 g/kg DM). Finally,...
