Soil properties after one year of interseeded cover cropping in topographically diverse agricultural landscape

Waste resulting from industrial poultry production systems is becoming an increasingly significant environmental problem in the US, threatening both soil and water quality. The goal of this study was to assess the spatial variability and interactions of selected soil properties (physical, chemical, and biochemical), viz., particle size, pH, enzymatic activity, Soil Organic Carbon (SOC), and Total Nitrogen (TN), across an agricultural landscape used for industrial poultry production. The measured soil properties were separated according to biochemical constituents and soil texture based on the first two principal components, accounting for approximately 60% of the variability across the site. These principal components were then used to generate soil surface maps, indicating areas of possible catalytic activity. Surface maps showed possible increases in biochemical activity around areas of stored poultry litter, suggesting the utility of these methods in determining changes to soil management.

Soil Fertility Status

Land cover changing would influence the availability of nutriens and others soil properties. In the forest areas, forest clearing would lead land degradation. KPHL Batutegi was catchment area for Batutegi dam. The ilegal logging that still occure in that area raising important question about the soil fertility status in that region. Its related to soil capability to the plant growth. The aims of this study was to get information about soil fertility status in two type of land cover, which was secondary forest and one year mixed coffee plantation. Soil sample was taking by purpose sampling on two type of land cover in KPHL Batutegi. One year mixed coffee plantation opened by illegal loging with fired. Intact soil samples were taken using the ring samples, while for the disturbed soil was done by the composite. Parameters observed were nutrients contain (N, P, and C-organic), pH, CEC, soil thickness, total pores and textur. The result showed that there no different on nutrient status and chemical soil properties between two land cover type. It was important from this study obtained that about 10 cm soil lost after one year land clearing from secondary forest to mixed coffee plantation.

Cumulative Co2 Emissions

Forestlands are widely distributed in the dominantly agricultural landscape in western Canada, and they play important ecological functions; such forestlands (e.g., shelterbelts) accumulate soil organic matter and may receive a substantial amount of nitrogen in the form of surface and subsurface runoff from adjacent croplands and become a significant source of emissions of greenhouse gases (GHGs) such as CO2, N2O, and CH4. Biochar and nitrapyrin applications could potentially mitigate GHG emissions, but their co-application in forest soils has not been studied. We investigated the effect of the application of biochars produced at low (300 °C; BC300) and high temperatures (700 °C; BC700) using canola (Brassica napus L.) straw and the effect of their co-application with nitrapyrin on GHG emissions and soil properties in a 35-day laboratory incubation experiment using forest soils collected from five shelterbelt sites. Results showed no significant interaction effect of biochar and nitrapyrin on the global warming potential (GWP) of the GHG emissions, and the GWP was 15.8% lower in the soil with nitrapyrin than without nitrapyrin application treatments. The GWP was significantly enhanced by BC300 addition due to a 26.9% and 627.1% increase in cumulative CO2 and N2O emissions, respectively, over the 35-day incubation. The GWP significantly decreased by BC700 addition due to a 27.1% decrease in cumulative CO2 emissions. However, biochar addition did not affect CH4 emissions, while nitrapyrin decreased CH4 uptake by 50.5%. With BC300 addition, soil-dissolved organic carbon and microbial biomass carbon increased by 26.5% and 33.9%, respectively, as compared to no biochar addition (CK). Soil pH increased by 0.16 and 0.37 units after the addition of BC300 and BC700, respectively. Overall, the effect of biochar and nitrapyrin was independent in mitigating GHG emissions and was related to the type of biochar applied and changes in soil properties.

Expert Classification

Cover cropping and no-till or minimum tillage are conservation farming techniques that have numerous benefits for the environment but are not always adopted by farmers because of risks of reduced yield and/or reduced profits. Precise and accurate methods of tracking conservation farming would improve the ability of researchers to maximize benefits and minimize risks. In this paper, satellite data is processed using an expert classification intended to identify cover crops in Wisconsin from the years 2009/2010 to 2018/2019. The results of a survey about farmers’ experiences with conservation farming practices is also summarized. The locations of cover cropped farms, identified in the survey, are used to assess the accuracy of the 2018/2019 map produced using the expert classification. The map was found to have an accuracy of only 51%. The survey results found that cover crops and no-till or minimum tillage did not tend to negatively affect yields or profits.

One Year

The agricultural landscape of French Guiana (Amazonia) is expected to undergo substantial change as a result of rapid population growth in the region. Such changes in the landscape will lead to the conversion of tropical forests into land destined for agricultural use. Little information is available on the effect of different agricultural systems on greenhouse gas (GHG) emissions in French Guiana. For our experiment, two hectares of forest were cleared, without the use of fire, at the Combi experimental site (sandy-clayey Ferralsol) at the end of 2008. After one year with legume and grass cover, the site was modified to include the following three fertilized agricultural systems: (1) Grassland (Brachiaria ruziziensis, mowed), (2) cropland (maize/soybean rotation) with disc tillage, and (3) cropland (maize/soybean rotation) with no-tillage in direct seeding. Soil N2O, CH4, and CO2 fluxes were measured with dark chambers from May 2011 to November 2014. Our results show that grassland was a significantly lower emitter of N2O but a significantly higher emitter of CH4 compared to the two cropland systems studied. We did not observe significant differences between the two cropland systems for N2O and CH4 fluxes. Measurements of the net ecosystem CO2 exchange would be useful to better compare the role of different agricultural systems as a source of GHGs.
