Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...

Developing Nitrogen fertilizer recommendations for corn using an active sensor
Producers often overapply N fertilizer to corn (Zea mays L.) because of the uncertainty in predicting the economic optimum nitrogen rate (EONR). Remote sensing represents a potential opportunity to reduce this uncertainty with an in-season assessment of crop N status. This study examines the relationship between EONR and reflectance from a ground-based sensor, and considers its potential for ...

Cattle manure application strategies effects on bahiagrass yield, nutritive value, and phosphorus recovery
Animal manure application based on crop N requirements often leaves excess P in the soil because of the differences in the N/P ratio in manures and that required by the plants. This experiment was designed to evaluate the effects of cattle (Bos taurus) manure applied alone or in combination with ammonium nitrate (AN) on bahiagrass (Paspalum notatum Flügge) dry matter (DM) yield, nutritive value, ...

Why buy modern organic fertilizer processing machine
The traditional artificial composting is not suitable for the development of modern agriculture. The simple composting method has a long time to treat livestock manure, a low content of organic fertilizer nutrients and a slow release. After years of development, modern organic fertilizer production machine has become the development trend of organic fertilizer production in the future. The ...

Observing the nitrogen cycle in a green manure trial on an organic farm
As part of a 5 year Federal Government funded Landcare project in the Gippsland area of Victoria, a number of on-farm trials have taken place. One of these trials was monitoring a range of green manures on a certified organic vegetable farm. The demonstration trialled and compared 6 different green manure crops each year for 3 years against a control. The control was immediately adjacent to the ...
