Abstract
Successful farm management requires the regular addition of nutrients (either as fertilizers or as organics) to maintain crop yields and quality. How much fertilizer do we apply and what kind of fertilizer is needed to give a balanced nutrition is an important queries ahead us. Soil and plant testing are the usual means to diagnose nutrient deficiency and recognizing soil with physical and chemical problems. Recommendations on fertilizer application rates are often given as part of the test. These recommendations are usually based on numerous fertilizer field trials that have been conducted over the years.
