“…This result reflected that K is not associated with structural components of plants, and it is normally found in the soluble form in the residues of cover plant [23] [27]. K release also depends less on microbiological decomposition of the residues, compared with N or P [27] [28] [29]. Thus, the extent of K release from September weeds is greater than N and P, and the release continued even during Winter (Figure 4).…”

Decomposition and nutrient release of the residue subsequent to mowing weeds remain poorly understood in persimmon orchards of South Korea. The litterbags including various weed residues were deposited on the soil surface under the tree canopy to simulate the fate of weeds mowed on 13 May, 13 July, and 13 September 2011 and 2012. Rate of decomposition and nutrient release of the residues depended on different mowing times. Residual dry mass (DM) of the 13 May weeds decreased by 17% -21% of initial DM during 1 month and by 63% -71% until 2 months after litterbag deposition, and they released 51% -67% of nitrogen (N), 54% -55% of phosphorus (P), and 92% -94% of potassium (K) of respective initial amount until the first 2 months. The 13 July weeds rapidly decomposed during the first month, accounting for 51% -64% of DM and released 49% -67% of N, 27% -54% of P, and 76% -77% of K. When mowed on 13 September, the weed residue decomposed slower and longer than the 13 May and 13 July weeds, losing 48% -51% of DM, 36% -39% of N, 60% -64% of P, and 70% -77% of K during the first 2 months but continuing an active decomposition even at 6 months after the deposition. The results indicated that time of supplemental fertilization should be adjusted depending on mowing times, and the mowing times be controlled to meet seasonal demand of persimmon trees for nutrients.

“…Decomposition process of the sod residues increases soil organic matter [30] and nutrient release in the sod residues imply an increase in minerals in the soil [29] [31]. Therefore, the nutrients, returned from the sod litter to soil, could directly determine the nutrient uptake of trees.…”

“…Applying cow manure as organic fertilizers for composting forage provides better results on plant growth when compared to inorganic ones (Vukobratović et al, 2008;Esmaeilian et al, 2012;Haghighat et al, 2012). Similar studies have also been carried out on rice cultivation (Kayeke et al, 2007;Jeon et at., 2011), potatoes (Davis et al, 1996) and maize (Baiwa et al, 2002;Tejada, et al, 2008;Dhima et al, 2009;Wijesinghe et al, 2009;Odhiambo, et al, 2010;Maobe et al, 2010;Talgre et al, 2012;da Silva et al, 2012). The objective of this study was to isolate and identify microbial decomposers from the manure of Palu local cow.…”

Abstract:Microbial decomposers are living things posessing an important role in outlining materials derived from organic compounds entering the environment as plant nutrients so that they arereusable by the greenery. This study was aimed to isolate and identify types of microbial decomposers from Palu local cow manure of Central Sulawesi, Indonesia. The results showed that in Palu local cow manure there were three types of microbial decomposers namely Lactobacillus sp, Actinomycetessp and Aspergillus sp. In Actinomycetes sp., the colony growth was very slow and firmly attached to the media surface after incubated for 7 days. It showed formation of mycelium spreading on the media surface with a serrated edge. Aspergillus sp.had morphological characteristics formed on media as follows: greenyellowcolonies; like-furtextures; green conidia; radiatconidia arrangement, uniseriat, fialidwhich almostfilled the entiresurface of vesicles; like-ballroundvesicle; coarse, thick-walled, and dark greenconidiophores.

“…In China, there will be a trend to integrate green manure in agricultural system as an alternative strategy for lowering chemical fertilizer usage and restoring a deteriorated field environment. Current research focuses on improving soil physical and biochemical properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14], contaminated soil rehabilitation [15][16][17][18][19][20][21][22], improving crop yield [13,[23][24][25][26], development of sustainable agricultural system [27][28][29][30][31][32] at the micro scale. However, developing green manure at a regional scale is especially affected by both human interventions and the natural soil properties.…”

Modelling the Spatial Expansion of Green Manure Considering Land Productivity and Implementing Strategies

Abstract:In modern sustainable agriculture, green manuring is increasingly emphasized for a reasonable land use management. However, the expansion of green manure is affected by a range of factors, such as soil geophysical properties and human intervention. This paper proposes an approach of spatial modelling to understand the mechanisms that influence green manure expansion and map the future distribution of green manure intercropped in the orchards in the Pinggu District, Beijing, China. We firstly classified the orchards into five grades according to a land productivity evaluation, and then considered two strategies for implementing green manure. Two scenarios were designed to represent the strategies: prioritizing low-productivity orchards to promote green manure intercropping (scenario 1) and prioritizing high-productivity orchards to promote green manure intercropping (scenario 2). The spatial expansion of green manure for 2020 was simulated at a resolution of a 100 × 100 m grid in the CLUE-S (the Conversion of Land Use and its Effects at the Small Region Extent) model. The two strategies led to quite different spatial patterns of green manure, although they were applied to the same areas. As a result, the spatial pattern of green manuring of scenario 1 was more concentrated than that of scenario 2. To summarize, the modelled outcomes identified the driving factors that affect green manure expansion at a grid scale, whereas the implementing strategies directly determined the spatial arrangements of green manuring at a regional scale. Therefore, we argue that the assessment of the driving factors and the prediction of the future distribution of green manuring are crucial for informing an extensive use of green manure.
