Urea is the most used nitrogen fertilizer in tropical agriculture, but when applied to soil surface, it can promote (N) losses by volatilization of ammonia (NH3). The present study aimed evaluate, under controlled laboratory conditions, N-NH3 from conventional N sources and compacted urea . Fertilizers were on surface a eutrophic Red Latosol clayey texture (Oxisol), previously moistened 60% its maximum water-retention capacity. Conduction experiment was completely randomized design with six...
Enhanced efficiency potassium fertilizers can be a management tool that is crucial to crop sustainability in maize (Zea mays L.). However, there need for studies aimed at validating the use of these different production environments. This study evaluate performance under sources and rates K through conventional enhanced soil with high available content. The experiment was carried out two years an Oxisol (605 g kg–1 clay) content (6.7 mmolc dm–3). Three were used, one (KCl), obtained by...
ABSTRACT The use of coated fertilizers is a strategy for improving fertilization efficiency and crop yield. However, further studies are needed to understand the dynamics different types K in soil. objective this study was evaluate soil columns after application conventional KCl other sources with coating (KCl-C) compaction (KCl-CC) combined additives polymers. experiment comprised four treatments, consisting three [conventional KCl, polymers (KCl-C), compacted (KCl-CC)], control without...
