Biofertilizers have been suggested as alternatives to synthetic fertilizers, which could reduce soil degradation brought on by excessive chemical fertilization and an impact the bacterial diversity community in soil. The of bacteria tea plantations treated with wheat straw compost have, however, received relatively little attention. In this research, a two-year field trial was run examine effec...

Effect of long-term application (ca. 30 years) of compost at different levels on humus composition of whole soils and their particle size fractions in a field subjected mainly to double cropping (barley and paddy rice) was investigated. Soil samples were collected from three plots of different types of management: (a) F plot, only chemical fertilizers containing N, P and K were applied; (b) F+L...

Background: Cattle manure (CM) is the most common organic fertilizer used by farmers. However, its usually slow decomposition leads to the use of chemical fertilizers. Therefore, experiments on nano- and micro-sized particles of CM were conducted to evaluate the possibility of accelerating its decomposition in soil. Methods: The effects of a sole application of CM in different sizes (nano-, mi...

Abstract Rice productivity in the tropics largely depends on fertilizers as soils are commonly low nitrogen and phosphorus. Some farmers this region cultivate rice using hand-broadcast method, which has resulted a yield. Therefore, on-farm experiment was conducted to compare performance yield of broadcasted transplanted production systems under different fertilizer combinations. The experimenta...

Fertilizer management plays an important role in obtaining satisfactory yields from maize. In addition, fertilizer management is essential for achieving sustainable agriculture and protecting the environment. This research was conducted by split plot experiment based on randomized complete block design with four replications. Main factor was integrated with chemical and biological fertilizers i...

introduction due to the development of sustainable agriculture and the reduction of utilizing chemical fertilizers, it is essential to use organic fertilizer. organic matter is vital to soil fertility and its productivity. to maintain the level of fertility and the strength of soil, organic matter levels should be maintained at an appropriate level. unfortunately, the level of organic matter in...

Sustainable agriculture can increase the efficiency of resource utilization, provide longer productivity and create a balance in the environment. A field experiment was conducted to study the use of organic and chemical fertilizers on biomass, essential oil content and essential oil yield as well as chemical compositions of Dracocephalum polychaetum Burnm in the first and second cutting. The tr...

introduction to achieve the higher economic yield of crop plants, supplying enough nutrients to plants is very important. moreover, nutrient uptakes by plants is influenced by the soil water contents. however, nowadays chemical fertilizer application is important agronomic factor that has significant effects on growth and quantity and quality of final yield, but traditional nutrient management ...

Nutrient losses to surface waters following fertilization contribute to eutrophication. This study was conducted to compare the impacts of fertilization with inorganic fertilizer, swine (Sus scrofa domesticus) manure or poultry (Gallus domesticus) litter on runoff water quality, and how the duration between application and the first runoff event affects resulting water quality. Fertilizers were...
