Prospect and production of coated controlled release fertilizer
Coated controlled release fertilizer The traditional chemical fertilizer, such as N or a certain proportion of N, P, K compound fertilizer, is coated with a special biological or chemical water soluble polymer film. Based on the characteristics of film thickness, particle radius, diffusion coefficient, nutrient composition and dissolution, the release rate and amount of fertilizer nutrient are ...

Zonejection: Conservation tillage manure nutrient delivery system
Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

Biosolids increase soil aggregation and protection of soil carbon five years after application on a crested wheatgrass pasture
Biosolids application to rangelands and pastures recycles nutrients and organic matter back to soils. The effects of biosolids (20 and 60 dry Mg ha–1) and N+P fertilizer on soil aggregate stability, bulk density, aeration porosity, and total C and N of stable aggregates were evaluated 4 and 5 yr after surface application to a crested wheatgrass [Agropyron cristatum (L.) Gaertn.] pasture in the ...

Interactive effects of landscape position and time of application on the response of spring wheat to fall-banded urea
The objective of this experiment was to quantify the effect of landscape position and time of application on the agronomic efficiency of fall-banded urea [CO(NH2)2] for spring wheat (Triticum aestivum L.) grown in the eastern prairie region of Canada. Landscape positions in this experiment were defined as high and low based on their relative elevations to one another within the field. Fertilizer ...

Barley yield and nutrient uptake for soil amended with fresh and composted cattle manure
Limited research exists on the long-term effect of fresh (FM) versus composted manure (CM) from beef cattle on barley (Hordeum vulgare L.) yield and nutrient uptake. Barley was grown (1999–2007) as silage on an irrigated clay loam soil in southern Alberta where organic amendments and fertilizer were annually applied for 9 yr in the fall of 1998 to 2006. The treatments were three rates (13, 39, 77 ...

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 ...

How to use organic fertilizer equipment to improve soil environment
Soil fertility has a great impact on crop yield and economic benefits. Soil fertility has declined and harvest has decreased, resulting in agricultural losses. Huaqiang equipment factory provides a complete set of professional organic fertilizer production equipment to help improve the agricultural soil environment. Three main reasons for the decline of soil fertility 1. The local land ...

Application of Biochar in Animal husbandry: Feed Additive
Animal husbandry plays a crucial role in meeting the global demand for animal products. However, it also generates significant environmental challenges, such as nutrient runoff and greenhouse gas emissions. To address these issues, researchers and farmers have been exploring innovative solutions, and one such solution is the application of biochar as a feed additive. This article will delve into ...
