Nutrient dynamics from broiler litter applied to no-till cotton in an upland soil
Applying broiler litter to the soil surface of a no-till field of cotton (Gossypium hirsutum L.) increases the potential loss of its nutrients via runoff and volatilization. An experiment was conducted over 3 yr on an upland Atwood silt loam soil (fine-silty, mixed, semiactive, thermic Typic Paleudalfs) near Pontotoc, MS, to determine the effect of broiler litter incorporation into the surface ...

Long-term fertilizer experiment network in China: Crop yields and soil nutrient trends
Results are summarized for the first 15 yr of an eight-site, long-term experimental network in China designed to assess the sustainability of cropping systems in environments representing 70% of Chinese cropland. Systems were wheat–maize double cropping (two crops per year) at four sites, wheat–rice double cropping, rice-based triple cropping, and wheat or maize single cropping. Without ...

Corn Production in the Bowen Food Basin - Case Study
In Bowen, Queensland, in 2010, Hibrix was compared with a high NPK mineral fertiliser program for the production of maize cv. Hycorn 675IT on an alluvial sandy loam soil irrigated via sub-surface drip tape. At commercial harvest, cobs from 20 randomly selected plants per plot from were harvested, weighed and the length, girth at the cob base and length of tip not filled with kernels was measured. ...

Soil properties and crop yields in response to mixed paper mill sludges, dairy cattle manure, and inorganic fertilizer application
The contribution of organic wastes to crop yields and soil fertility may be influenced by their composition and the soil type. This 6-yr study (2001–2006) evaluated the effects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha–1), dairy cattle manure (DCM) (36 Mg ha–1) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on ...

NPK compound fertilizer production line manufacturers talk about sulfur use methods
NPK compound fertilizer production line manufacturers often use sulfur to reduce soil pH value and improve saline alkali soil in agriculture. However, the use of sulfur as nutrient fertilizer in agricultural production has not attracted people's attention until recently. Sulfur is an inert, insoluble yellow crystalline solid. Commercially, it can be stored in the open air, and it remains ...

Difference between the production machines of organic fertilizer and compound fertilizer
The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in ...
