“…Crop residue is returning not only can increase crop yields, but it also can enhance soils' resistance to wind and water erosion [6,7]. Animal manures, such as pig manure with ample N, P and K, are valuable resources to supply the needed plant nutrients and organic matters [2,4,5,8,9]. Therefore, rice straw and fresh pig manure are commonly used as organic amendments in the red soil region of China.…”

Red soils are widespread throughout subtropical and tropical regions and are the most important resources for grain production in South China. Application of chemical fertilizers alone or chemical fertilizers combined with organic amendments is commonly practiced to improve physicochemical properties and fertility for red soils. This chapter summarizes the findings of a -year long-term field experiment conducted in the red soil region of south central China. Changes in soil pH, soil organic matter OM , nitrogen N , phosphorus P , and aggregate distribution and stability as affected by the long-term fertilization treatments were examined and discussed. Combined application of chemical fertilizer and rice straw or pig manure significantly increased soil pH in the first years, but soil pH decreased linearly at a rate of . -. unit yearly since then. Soil total N and total P content significantly increased during the long-term fertilization, and the effects of pig manure addition on N and P build-up were greater than that of rice straw addition. In contrast, soil total potassium K contents significantly decreased by the long-term fertilization. There was a significant difference between the effect of rice straw addition and pig manure amendment on various aggregate size distribution in the red soil.

“…Richards et al (2011) found that the application of fertilizers for several years significantly increased organic matter content and the concentrations of available forms of Fe, Cu, Mn, Zn and Mo in the soil and also find significant correlations between total amounts of micronutrients applied through organic fertilizer and available forms of those micronutrients in the soil. As organic fertilizer did not impact soil pH, which greatly affects the availability of micronutrients, the increase of micronutrient concentrations is probably a result of the interaction between metal ions and various organic acids created during the mineralization of applied organic matter, and formation of chelated complexes (Leita et al, impact on soil fertility and yield 1999).…”

“…Eghball et al (1997) remark that in comparison to farmyard manure, a considerable part of readily degradable organic C and N in composts is lost during composting, while remaining C and N are found in more stable forms which are more resistant to mineralization and have weaker affinity to metal ions in the creation of chelated complexes. Besides this, by applying farmyard manure significantly more organic C was incorporated into the soil than was the case with compost (mushroom compost and vermicompost) treatments (Table 2), which could also have led to farmyard manure having a higher impact on available micronutrient concentrations than composts (Richards et al, 2011). The differences between the two mulching methods could have arisen from higher soil temperatures, more intensive mineralization (Fig.…”

The objective of this research was to quantify the effect of the application of organic fertilizers: farmyard manure, vermicompost, spent mushroom compost, under two different ground cover management systems (black polyethylene and wheat straw mulch) on soil nutrient levels and strawberry yield during a two-year production cycle. The application of organic fertilizers, in the amounts equivalent to 170 kg ha -1 N, had the greatest impact on the concentration of available phosphorus, which was significantly higher on fertilized plots than on the control even two years after the application. The plots fertilized with farmyard manure and mushroom compost had higher concentrations of available potassium than the control, while the application of vermicompost did not affect the concentration of available potassium in the soil. The application of composts did not affect the concentration of available microelements in the soil, while the concentrations of Fe, Zn and Cu in the year of the organic fertilizers application were significantly higher on farmyard manure fertilized plots than on the control. The application of all three organic fertilizers had a significant effect on the mineral N concentration in the soil only in the year of the application and the following spring. However, the plots covered with polyethylene mulch had a higher mineral N concentration than the control at all sampling times. The concentration of available microelements was significantly higher in soil covered with black polyethylene mulch than in soil covered with straw mulch. Preplant application of organic fertilizers led to increase of yield, ranging from 14.3% in vermicompost treatmet to 17.3% in the farmyard manure treatment in relation to the control, only in the 1 st fruiting year. However, the application of polyethylene mulch facilitated a higher strawberry yield than straw mulch in both fruiting years.

“…Phosphorus concentrations in runoff were significantly correlated with K ( r = 0.54) and all of the other metals in runoff, except for Zn (Table 3). This is understandable because poultry litter and cattle manure contain relatively high concentrations of P and metals, and hence manure additions would increase the availability of all metals (He et al, 2009; Richards et al, 2011). It should be mentioned that the current research was originally planned to evaluate the effects of buffers and grazing management on P runoff, and a manuscript concerning those results is in preparation.…”

Effects of Grazing Management and Buffer Strips on Metal Runoff from Pastures Fertilized with Poultry Litter

et al. 2017

Metal runoff from fields fertilized with poultry litter may pose a threat to aquatic systems. Buffer strips located adjacent to fields may reduce nutrients and solids in runoff. However, scant information exists on the long-term effects of buffer strips combined with grazing management on metal runoff from pastures. The objective of this study was to assess the 12-yr impact of grazing management and buffer strips on metal runoff from pastures receiving poultry litter. The research was conducted using 15 watersheds (25 m wide and 57 m long) with five treatments: hayed (H), continuously grazed (CG), rotationally grazed (R), rotationally grazed with a buffer strip (RB), and rotationally grazed with a fenced riparian buffer strip (RBR). Poultry litter was applied annually in spring at 5.6 Mg ha. Runoff samples were collected after every rainfall event. Aluminum (Al) and iron (Fe) concentrations were strongly and positively correlated with total suspended solids, indicating soil erosion was the primary source. Soluble Al and Fe were not related to total Al and Fe. However, there was a strong positive correlation between soluble and total copper (Cu) concentrations. The majority of total Cu and zinc was in water-soluble form. The CG treatment had the highest metal concentrations and loads of all treatments. The RBR and H treatments resulted in lower concentrations of total Al, Cu, Fe, potassium, manganese, and total organic carbon in the runoff. Rotational grazing with a fenced riparian buffer and converting pastures to hayfields appear to be effective management systems for decreasing concentrations and loads of metals in surface runoff from pastures fertilized with poultry litter.
