To assess the impact of S fertilization on bahiagrass (Paspalum notatum) quality and Cu metabolism in cattle, two studies were conducted during the summer grazing season (1999 and 2000). Pasture replicates (16.2 ha; n = 2/treatment) received the same fertilizer treatment in each growing season, consisting of 1) 67 kg N/ha from ammonium sulfate (AS), 2) 67 kg N/ha from ammonium nitrate (AN), and...

Mineral fertilization is considered to be useful for improving soil fertility and yields. However, its use linked global warming water pollution by rapid mobilization. On the other hand, organic recommended maintain or improve carbon total nitrogen stocks while contributing climate change mitigation. The main goal of this study was assess effect two different fertilizer types, mineral organic, ...

ABSTRACT The objective of this study was to evaluate nutrient export, nutritional balance and macronutrient recovery rate in ‘Gigante cactus pear under different fertilization doses, spacings configurations during three production cycles. 72 treatments were arranged a randomized block design with repetitions, two the plots (triple quadruple row), subplots (3.00 x 1.00 0.25 m; 3.00 0.16 m 0.125 ...

Carbon sequestration has been proposed as a way to mitigate the impact of CO2 on climate. At COP21, ‘4 per 1000 Soils for Food Security and Climate’ initiative was launched with goal increase global soil organic carbon (SOC) stocks by 4‰ year. The Thyrow long-term field experiment DIV.2 chosen determine feasibility this 4 under dry sandy conditions in Eastern Germany. effects different fertiliz...

Zinc deficiency is causing malnutrition for nearly one third of world populations. It is especially relevant in cereal-based diets in which low amounts of mineral and protein are present. In biological systems, Zn is mainly associated with protein. Cereal grains contain the highest Zn concentration during early developmental stage. Although hordeins are the major storage proteins in the mature ...
