A green slow-release fertilizer composition based on urea-modified hydroxyapatite nanoparticles encapsulated wood
In this paper we describe a strategy for sustained release of nitrogen into the soil. Specifically, ureamodified hydroxyapatite nanoparticles were encapsulated under pressure into cavities of the soft wood of Gliricidia sepium. Nitrogen release of the nanofertilizer composition was studied using soil from three elevations in Sri Lanka (pH 4.2, 5.2 and 7) and compared with that of a commercial f...
متن کاملInfluence of polymer-coated slow-release urea on total tract apparent digestibility, ruminal fermentation and performance of Nellore steers
OBJECTIVE Two experiments were performed to evaluate the effects of coated slow-release urea on nutrient digestion, ruminal fermentation, nitrogen utilization, blood glucose and urea concentration (Exp 1), and average daily gain (ADG; Exp 2) of steers. METHODS Exp 1: Eight ruminally fistulated steers [503±28.5 kg body weight (BW)] were distributed into a d 4×4 Latin square design and assigned...
متن کاملEffects of slow-release urea on ruminal digesta characteristics and growth performance in beef steers.
Two experiments were conducted to evaluate the effects of slow-release urea (SRU) versus feed-grade urea on ruminal metabolite characteristics in steers and DMI, gain, and G:F in growing beef steers. Experiment 1 used 12 ruminally cannulated steers (529 +/- 16 kg of BW) to monitor the behavior of SRU in the ruminal environment. Compared with feed-grade urea, SRU decreased ruminal ammonia concen...
متن کاملEffect of urea treated paddy straw supplementation on the performance of crossbred cows
An experiment was conducted on eight crossbred cows of similar age (4-5 yr) and body weight (306.96 ± 12.57 kg) to elucidate the effect of urea treated paddy straw supplementation on their feed intake, milk production and blood biochemical profiles. Crossbred cows were randomly divided into two equal groups and fed a concentrate mixture and paddy straw to meet their nutrient requirement. Group ...
متن کاملEffects of a slow-release urea product on performance, carcass characteristics, and nitrogen balance of steers fed steam-flaked corn.
Two experiments were conducted to examine the impact of source, urea (U) or Optigen II (OP), and level of dietary NPN on performance (Exp.1) and N balance (Exp. 2) of growing cattle. Sixty Angus crossbred steers (initial BW = 353 ± 13.9 kg) were used to evaluate performance, and fed 1 of 3 steam-flaked corn based diets: U (U(1.2), 1.2% NPN), OP (OP(1.3), 1.3% NPN), or OP without cottonseed meal...
