The economically optimum fertilizer rate is less than the rate where highest yield is achieved due to the concept of diminishing returns. The type of fertilizer must be considered because fertilizers differ in their cost, effectiveness and efficiency, as is the case when comparing granular and liquid fertilizer forms.

Twelve NPS fertilizer rates were laid down on Randomized Complete Block Design (RCBD) with three replications to identify the optimum rates of NPS where maximum yield of Adama Red onion variety can be obtained. The results of the experiment revealed that most of the growth and yield parameters of onion were significantly affected by NPS fertilizer. band P and K fertilizer rates compared with broadcast fertilization in low-testing soils. Iowa research across many years on many fields indicates that this is not the case. Less than optimum fertilizer rates, no matter the placement method, reduce total return to fertilization, but do increase the return per pound of nutrient applied.

Nitrogen rate trials are often performed to determine the economically optimum N application rate. For this purpose, the yield is modeled as a function of the N application. The regression analysis is commonly used to estimate the modeled functions and the economic optimum rate, 𝑁opt. However, computer programs do not calculate confidence intervals for 𝑁opt derived from quadratic yield Thus, our guidelines for manure application are based on optimal nutrient rates needed - which is known from fertilizer experiments - and how much plant-available nutrient will be …

Successful use of manure fertilizer requires adjusting application rates to account for reduced nutrient availability. Sometimes manure management strategies can take advantage of the slow release characteristics of organic nitrogen and phosphorus in manure to help reduce nutrient losses from fertilizer applications. The optimum fertilizer requirements, based on the 2002 prices for the fertilizers applied and the crop, are 1½ bags of AS, 5 bags of SSP and ½ bag of MOP per hectare. Based on the 2002 fertilizer and crop prices, a VCR of 3.6 can be obtained (Table 39). Groundnut is a major crop in the Guinea and Sudan Savannah Zones.

In terms of turf survival, the answer probably is no, since If the fertilizer rate calls for an application of half a pound (.5 lbs) of Nitrogen per 1000/sq.ft., you will need to know how much fertilizer to apply to deliver that amount. If you know a simple formula, you can get the fertilizer rate correct regardless of the fertilizer analysis.

    Apr 07, 2017 · From an environmental standpoint, the reduced crop recovery of N fertilizer at rates in excess of optimum yield can result in a greater potential N losses. Many agronomists use target crop yields and nutrient removal to estimate crop N fertilizer requirements. But developing best N fertilizer recommendations is not always that simple!
