ABSTRACT: Food security assurance to meet the demands of increased population growth requires a proportional increase in milk and meat production which, in turn, depends on animal nutrition. Assessing foliar application of micronutrients for production of substantive quantities of good quality forage must be a goal of modern, profit-oriented, sustainable agriculture and plants with better competitive ability as compared to weeds. This meta-analysis made a quantitative and qualitative analysis of the impact of foliar feeding of micronutrients (iron, zinc, copper, sulfur and boron) on forage crops under varying pedo-climatic conditions. Weighted and unweighted meta-analyses were performed on 139 studies to evaluate 19 independent variables (9 qualitative, 5...

ECONOMIC RETURNS FROM REDUCING POULTRY LITTER PHOSPHORUS WITH MICROBIAL PHYTASE
Provedor de dados: 31
Autores: Bosch,   Darrell J.; Zhu,   Minkang; Kornegay,   Ervin T.
Requiring that crop applications of manure be based on phosphorus content (P-standard) could increase poultry litter disposal costs. Microbial phytase reduces litter P content and could reduce litter disposal costs under a P-standard.  For a representative Virginia turkey farm, phytase costs $2,500 and could increase value of litter used for fertilizer on the turkey farm by $390 and reduce supplemental P feed costs by $1,431. Based on assumed litter demand and supply, estimated litter export prices with phytase could exceed export prices without phytase by $3.81 per ton. Phytase net returns to the farm are an estimated $ 1,435.

Assessing the potential for beneficial diversification in rain-fed agricultural enterprises
Provedor de dados: 31
Autores: Kandulu,   John.
Climate change and climate variability induce uncertainty in yields, and thus threaten long term economic viability of rain-fed agricultural enterprises. Enterprise mix diversification is the most common, and is widely regarded as the most effective, strategy for mitigating multiple sources of farm business risk. We assess the potential for enterprise mix diversification in mitigating climate induced variability in long term net returns from rain-fed agriculture. We build on APSIM modelling and apply Monte Carlo simulation, probability theory, and finance techniques, to assess the potential for enterprise mix diversification to mitigate climate-induced variability in long term economic returns from rain-fed agriculture. We consider four alternative farm...
