Abstrak. Menurunnya produktivitas lahan sawah di Indonesia sebagian besar disebabkan oleh yang terdegradasi, dicirikan kandungan bahan organik rendah. Cara bisa dilakukan dalam meningkatkan yaitu menggunakan terdiri dari biochar sekam padi, pupuk kandang kotoran sapi dan ayam. Tujuan penelitian ini, : mengetahui pengaruh pemberian biochar, ayam terhadap perubahan sifat kimia, pertumbuhan produk...

This work aimed at assessing water percolation through a solid cow manure leach bed in dry batch AD processes. A laboratory-scale percolation column and an experimental methodology were set up. Water behaviour was modelled by a double porosity medium approach. An experimental procedure was proposed to determine the main hydrodynamic parameters of the multiphase flow model: the porosity, the per...

in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

Organic amendments may improve the quality of acidic tropical agricultural soils with low organic carbon contents under conventional management (mineral fertilization and irrigation) in Southeast Asia. We investigated effect biochar, compost their combination on maize growth yield, soil physical, biological chemical properties at harvesting time four sites three countries: Thailand, Vietnam Lao...

The objectives of this study were to estimate the prevalence of Mycobacterium avium subsp. paratuberculosis (MAP) among deer and rabbits surrounding infected and noninfected Minnesota dairy farms using fecal culture, and to describe the frequency that farm management practices were used that could potentially lead to transmission of infection between these species. Fecal samples from cows and t...

Background: In cereals based legume cropping system more importance and intensification are given to first crop (cereals) as compared succeeding crops. Hence, crops yield got reduced due grown in low fertile soils. Productivity of green gram have declined or stagnated recent years though we grew high varieties, marginal lands with nutrient moisture. Biochar is organic substance that highly pers...
