The economic feasibility of using composted manure from western Kansas feedlots in combination with commercial N in the production of irrigated grain sorghum [Sorghum bicolor (L.) Moench] was evaluated. Effective disposal of large quantities of manure from large scale feedlots has been a concern. ...
aUsing fresh horse manure in soil gave many vegetables a harsh flavor so it was first composted by mixing in some soil (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 sho...
Here is Ryan showing Gavin how it’s done – the machine needs a lot of control to maneuver it through the soil beds. Zoe also takes a turn using the rototiller. This vegetable garden is quite large, so it takes time to rototill the entire space, but it’s well worth the effort. ...
Is Rye grass (from green manure planting) to be used in the same way, if it's not being dug in? Also, an old timer gardener told me that using bio mulch uses up your soil nutrients as it breaks down so you are robbing your veggies (or changing the soil like my bark mulch) - ...
Then if anything is left by spring it can be raked up and made into low heaps or even trench composted for summer crops such as squash and melons. I never make real compost heaps, I just sheet compost everything or use weeds and trimmings as mulch. Look into the possibility of ...
The production function estimate was used to determine the combination of composted manure and commercial N, which maximized net returns. The results suggest that a compost application rate of 15t ha1 with 20 kg ha1 of commercial N would be economically feasible when the price of commercial N,...
The GHG budget based on directly measured emissions indicates that the application of composted manure, in combination with reduced fertilizer rate, was always superior to stockpiled manures. Compost treatments showed from 9 to 90% less GHG emissions than stockpiled manure treatments. However, higher ...

Similarly, Suthar [42], using vermicompost produced from crop residues with cow manure in the cultivation of A. sativum, showed that an increase in vermicompost dose affected the average leaf length but had no effect on the number of leaves per plant. Alemu et al. [43], as a result of ...
Management of equal amounts of livestock manure is considered in both scenarios. Before entering the fermenters, hay, green cuttings, and the local organic wastes undergo SEP. Solid manure is added directly to the fermenter. The biogas generated in the fermenters is fed into a CHP module. ...
