Cool Season Fertilizing Time is Now
Cool season root and soil fertilizing is the best way to maintain year-round nutrient levels for deciduous trees, plants, and shrubs. In addition, cool season fertilizing prepares plants to grow with gusto as soon as warmer Spring temperatures return. Biofeed Solutions, Inc. has prepared this information to better explain. We will cover dormant root behavior, NPKs and Micro-nutrients.The cool ...

Soil properties and crop yields in response to mixed paper mill sludges, dairy cattle manure, and inorganic fertilizer application
The contribution of organic wastes to crop yields and soil fertility may be influenced by their composition and the soil type. This 6-yr study (2001–2006) evaluated the effects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha–1), dairy cattle manure (DCM) (36 Mg ha–1) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on ...

NPK compound fertilizer production line manufacturers talk about sulfur use methods
NPK compound fertilizer production line manufacturers often use sulfur to reduce soil pH value and improve saline alkali soil in agriculture. However, the use of sulfur as nutrient fertilizer in agricultural production has not attracted people's attention until recently. Sulfur is an inert, insoluble yellow crystalline solid. Commercially, it can be stored in the open air, and it remains ...

Difference between the production machines of organic fertilizer and compound fertilizer
The internal quality of organic fertilizer mainly depends on raw material fermentation and product formula. The key factors affecting the fermentation of organic fertilizer production process are: microorganism, carbon nitrogen ratio, carbon phosphorus ratio, water content, pH value, aeration control. If one factor is not properly controlled, the whole fermentation will be affected, resulting in ...
