Ammonia Volatilization from Urea-Application Influenced Germination and Early Seedling Growth of Dry Direct-Seeded Rice
Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice. To directly examine soil ammonia volatilization and its damage to seed germination and early seedling growth of dry direct-seeded rice when urea is applied at seeding, two Petri-dish incubation experiments and a field experimen...
متن کاملAmmonia volatilization from surface-banded and broadcast application of liquid dairy manure on grass forage.
Manure can provide valuable nutrients, especially N, for grass forage, but high NH, volatilization losses from standard surface-broadcast application limits N availability and raises environmental concerns. Eight field trials were conducted to evaluate the emission of NH, from liquid dairy manure, either surface broadcast or applied in narrow surface bands with a trailing-foot implement. Manure...
متن کاملBlending Urea with Organic Materials Possessing Antimicrobial Property on Nitrification and Ammonia Volatilization in a Tropical Soil
Different organic materials possessing antimicrobial properties have the ability to retard nitrification. Nitrification retarders could be successfully used to improve fertilizer efficiency if the retarders do not increase ammonia volatilization as well. The main objective of this study was to find whether any locally available organic materials namely cow dung, seed crush of Syzygium cumini, L...
متن کاملAmmonia Volatilization from Dairy and Poultry Manure
Ammonia volatilization is a major N loss process for surface-applied manures and urea fertilizers. The lost ammonia is important for both agricultural and non-agricultural ecosystems because it: i) is a direct loss of plant available N to the farmer, ii) reduces the N:P ratio in manure, which accelerates P build-up in soils, and iii) contributes to eutrophication in aquatic and low-N input ecos...
متن کاملSilicate and Phosphate Combinations for Marandu Palisadegrass Growing on an Oxisol
One of the greatest problems for pasture establishment and maintenance are the extremely low concentrations of available phosphorus in soils. The objective of this study was to evaluate the influences on productive and physiologic attributes during Marandu palisadegrass (Brachiaria brizantha) establishment, following changes in phosphorus availability in the soil through the applications of pho...
