A well-drained soil in N-fertilized dairy pasture was amended with particulate organic carbon (POC), either sawdust or coarse woody mulch, and sampled every 4 wk for a year to test the hypothesis that the addition of POC would increase denitrification activity by increasing the number of microsites where denitrification occurred. Overall mean denitrifying enzyme activity (DEA), on a gravimetric...

BACKGROUND: Application of plant mulches plays a significant role in development and expansion of sustainable farming systems. OBJECTIVES: Assessment effect of chemical and non-chemical weeds management methods on weeds density and biomass and the properties of soil, including microbial biomass carbon (MBC) and soil organic carbon (SOC) in potato cultivation. ...

Background: The application of biochar as a soil amendment has achieved popularity and has been found to improve considerably soil nutrient status and plant productivity in low fertile soils. Methods: This study used two different methods to apply sewage sludge and sewage sludge biochar with three replicates in a completely randomized block design. The experiment included (1) control, (2) mulc...

wick et al., 1983). Living plants do not actively release high amounts of ITCs (Börner, 1961), because glucosiThe allelopathic potential of isothiocyanates (ITC) released by nolates are located in the vacuole and myrosinase is turnip–rape mulch [Brassica rapa (Rapifera Group)–Brassica napus L.] was evaluated. Six different ITCs were identified from chopped bound to the cell wall (Björkman, 1976...

Expanding agricultural land by using sloping dry can be detrimental to the environment due soil erosion and degradation. However, cover crops one of technologies applied reduce these risks. Arachis pintoi is that used as bio mulch on land. The study aimed evaluate effect A. nutrient contents maize plant growth at different slopes. A nested randomized block design was in study. Two levels main f...

Beans are vegetables that widely cultivated in Indonesia. The growth of beans is determined by internal and external factors. factor affects the availability nutrients. Vermicompost an organic fertilizer can be used to increase growth. Research has been carried out on Analysis Bean (Phaseolus vulgaris) Growth Due Treatment Different Types Mulch. This study aims determine: (1) effect type mulch ...

Cultivation of soybean is currently planted using ground cover as a solution to increase crop productivity. So it necessary research the effect various types organic mulch on growth and yield soybeans (Glycine max L. Merril). This study aims determine was laid out in Randomized Block Design 1 factor, which composed 6 levels, with 5 replications, so there are 30 experimental units. There no mulc...
