Plots received several rates of fresh (FP), dried (DP), or composted (CP) poultry () manure, composted () (CC) manure, nitrate (AN), or no N. Crop yields and N uptake from plots where CC was applied were undistinguishable from controls in most years, whereas poultry manures ...
P added with fresh and composted manure was adsorbed to a lesser degree on the soil than the added inorganic P. Fresh manure reduced P adsorption more than did composted manure. Both types of manure contained simple organic acids, which have earlier been shown to influence P sorption. The ...
(a good idea because otherwise a great deal of ammonia would escape the heap). Market gardeners raising highly demanding crops like cauliflower and celery amended composted short manure by the inches-th 使用新鲜的马肥料在土壤给了许多菜一个苛刻的味道,因此它通过混合在一些土壤一个好 (想法首先堆肥,...
Extractable ortho-P concentrations declined by up to 37% in fresh manure and 49% in composted manure with the application of 200 g co-amendment kg -1 manure (dry weight basis), and lower extractable ortho-P levels persisted during a 6 week laboratory incubation. In a greenhouse experiment, ...
Transport of Residual Nutrients Through Intact Soil Cores Amended With Fresh or Composted Beef Cattle Manure for Nine Years. Although fresh beef cattle (Bos Taurus) manure has traditionally been applied to cropland in Western Canada, application of composted manure has recently i... Miller,J J.,...
In particular, fresh chicken manure yielded the highest crop yield of lettuce, but also increased the abundance of ARGs considerably. Genes encoding mobile genetic elements (tnpA, intI1) were positively correlated with ARGs, suggesting a risk of dissemination of antibiotic resistance via HGT in ...
Livestock manure-derived amendments can be beneficial for agricultural soil quality, as they can increase the content of soil organic matter and nutrients, stimulate microbial activity and biomass, and enhance crop yield. Here, we studied the impact of six different manure-derived amendments, ...
Growth traits and yields of maize (Zea mays) are described for varying fertilizer treatments (fresh cow manure, composted manure, inorganic NPK). Relative N-uptake is 9, 28, and 46% for compost, fresh manure and NPK, respectively. Growth rate and yields are correlated significantly with plant...
Effects of Fresh and Composted Dairy Manure Applications on Alfalfa Yield and the Environment in Arizona. Agron. J. 98:80-84.Martin, E.C., D.C. Slack, K.A. Tanksley, and B. Basso. 2006. Effects of fresh and composted dairy manure applications on alfalfa yield and the envi- ronment ...
Fresh beef cattle (Bos taurus) manure has traditionally been applied to cropland in southern Alberta, but there has been an increase in application of composted manure to cropland in this region. However, the quality of runoff under fresh manure (FM) versus composted manure (CM) has not ...
