Question: What Is A Good Crop Productivity Index?

What do soil productivity numbers mean?

The PI uses family-level Soil Taxonomy information, i.e., interpretations of taxonomic features or properties that tend to be associated with natural low or high soil productivity, to rank soils from 0 (least productive) to 19 (most productive)..

How can soil productivity be improved?

You can improve soil organic matter basically by two ways: adding more organic matter, and not losing the organic matter that you already have. You can add organic matter by growing productive, healthy crops in a diverse rotation.

How do humans affect soil?

Nonetheless, some human activities have clear direct impacts. These include land use change, land management, land degradation, soil sealing, and mining. … This in turn leads to loss of soil carbon and other nutrients and to changes in soil properties and in soil biodiversity.

What is soil productivity rating?

The optimum productivity index (PI) can be used to determine the prime agricultural class of any soil type in the state. The rating system determines an A, B, and C class of soil. Productivity ratings of 133-147 represent Class A, 117-132 represent Class B, and ratings of 100-116 represent class C.

It is what most consider a measure of farmland quality. Higher quality farmland is taxed higher than lower quality farmland which is determined by the CSR of the farm.

What is fertilized soil?

Fertilization is supplementing the existing soil with additional, needed nutrients. Fertilizing wisely increases yield, quality (nitrogen content and digestibility), and profits. There are three basic ways to replenish the nutrients removed from the soil. One way is to recycle nutrients, mainly by way of animal waste.

What does CSR2 stand for?

Knowing your farm’s Corn Suitability Rating indexKnowing your farm’s Corn Suitability Rating index (CSR2) provides you with valuable insight into its productivity. CSR2 is a tool used in setting cash rental rates and computing a farm’s sale value. In 2013, the system for CSR was updated to CSR2 values.

What does Nccpi mean?

National Commodity Crop Productivity IndexThe National Commodity Crop Productivity Index (NCCPI) model is a national soil interpretation that is not intended to replace other crop production models developed by individual states.

What is a good csr2 rating?

Corn Suitability Rating 2 remains an index to the inherent soil productivity of each kind of soil for row crop production. The index is scaled from 100, for the most productive soils, to 5 as the least productive.
