Biochar is a material produced by the pyrolysis of agro-industrial waste, which has become one most promising management tools to improve soil quality. The aim was determine effects incorporating biochar from different coffee wastes in sandy soil, cropped with maize, on chemical and microbial attributes. experiment followed factorial design 2 × 3 + 1 two types biochar, including ground (CG) or ...

A simple method based on some statistical measurements for Latin handwritten digit recognition is proposed in this paper. Firstly, a preprocess step is started with thresholding the gray-scale digit image into a binary image, and then noise removal, spurring and thinning are performed. Secondly, by reducing the search space, the region-of-interest (ROI) is cropped from the preprocessed image, t...

Fingertips detection has been used in many applications, and it is very popular and commonly used in the area of Human Computer Interaction these days. This paper presents a novel time efficient method that will lead to fingertip detection after cropping the irrelevant parts of input image. Binary silhouette of the input image was generated, using HSV color space based skin filter and hand crop...

During 1995 to 1997, the efficacy of early tactical management of mouse populations in a project based on grain-growing farms in Victoria, Australia was examined. Farmers modified their management practices of crops (at sowing, harvest, and land preparation), and managed habitats on the boundary of cropped land (such as fencelines) and around farm buildings. One management practice examined was...

approximate conditions in natural ecosystems, managed ecosystems are characterized by a substantial organic matter export mainly as harvest (e.g. Schulze et al. 2009). Given that currently ca. 12% of the global land area of ca. 13.4 Gha is cropped and ca. 26% used as pastures, the role of carbon exports needs to be addressed or, in case I misunderstood, the procedure of how inputs were derived ...

In Arkansas wheat is commonly grown either in rotation or double cropped with soybean. Surveys from 1986 to 1988 identified 18 phytoparasitic nematode species in Arkansas wheat fields. The frequency of occurrence, as a percentage of the total number of samples (199), for the following nematodes was Heterodera glycines 43%, Quinisulcius acutus 40%, Pratylenchus scribneri 37%, Helicotylenchus pse...

Corn was an important crop for people who lived in the area that became Illinois before the Europeans first set foot here; it was the staple food crop of the people who lived in the Cahokia area some 1,000 years ago. It was a crop of choice when Europeans settled and started to farm in Illinois, and acreage in the state first reached 10 million acres in 1895. Acreage over the past 100 years has...

The intensification and expansion of modern agriculture is amongst the greatest current threats to worldwide biodiversity. Over the last quarter of the 20th century, dramatic declines in both range and abundance of many species associated with farmland have been reported in Europe, leading to growing concern over the sustainability of current intensive farming practices. Purportedly sustainable...

Abstract Background Knowledge of soil aggregate formation and stability is essential, as this important for maintaining functions. Aims This study aimed to investigate the influence organic matter (OM), content pedogenic iron (Fe) (oxyhydr)oxides, size on aggregates in arable soil. Methods To end, Ap Bt horizons a Luvisol were sampled after 14 years bare fallow, results compared with control fi...
