What is land productivity index

Mar 6, 2018 Land expert Kent Morris, ALC, explains how you can use a site index as a way to measure the productivity of your forest land. This is yet another very productive parcel of land currently utilized for hay production. However with over 96% considered cropland with a Soil Productivity Index ( 

This output value may be compared to many different types of inputs such as labour and land . These are called partial measures of productivity. Agricultural productivity may also be measured by what is termed total factor productivity (TFP). This method of calculating agricultural productivity compares an index of agricultural inputs to an The 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. At present, NCCPI is used in the National Soil Information System (NASIS) environment and is not available through the Soil Data Mart. It iii. The Productivity Index: Let us represent the productivity index in the given year to 1.00 in the base year by M n. o. Then, for the three departments or processes, we have . However, since the ratio m 0 /m n gives the pro­ductivity index process by process, weighted for out­put, they would give a productivity index for the three CSR2 will be the new index of soil productivity in Iowa. It will be supported and updated yearly on the NRCS Web Soil Survey internet site. CSR numbers will still be around for people to compare how things have changed in the classification of the land productivity potential on their farm. The classic productivity definition is “a way to measure efficiency.” In an economic context, productivity is how to measure the output that comes from units of input. Farming makes for a good example: One acre of land that produces 10 pumpkins? That’s not very productive. But one acre of land that produces 2,000 pumpkins? Bulletin 811 Optimum Crop Productivity Ratings for Illinois Soils University of Illinois College of Agricultural, Consumer and Environmental Sciences Office of Research This publication was prepared by K.R. Olson, Professor of Soil Conservation, Soil Management and Pedology (NRES), and J.M. Lang, Associate Agronomist (NRES).

The Storie Index Rating was an early attempt at quantitative land evaluation and an example of parametric approach. The system has been widely applied around  

Productivity indexes (PIs) published in Bulletin 811, entitled Optimal Crop Productivity Ratings for Illinois Soils, often are used to quantify yield potential of Illinois soils. This publication gives PIs for different soil types. Higher PIs typically are associated with higher corn and soybean yields. The productivity index is a measure of the well potential or ability to produce and is a commonly measured well property 1. The symbol J is commonly used to express the productivity index; as well as, being the preferred symbol by the Society of Petroleum Engineers. productivity. A few criteria relate to factors that can limit use of the land (e.g., surface boulders). All criteria used in the index affect crop culture and production and are referred to as factors affecting inherent productivity. The rating indices can be obtained through a computer program in NASIS. This output value may be compared to many different types of inputs such as labour and land . These are called partial measures of productivity. Agricultural productivity may also be measured by what is termed total factor productivity (TFP). This method of calculating agricultural productivity compares an index of agricultural inputs to an Soil is a living, dynamic resource that supports plant life. It is made up of different size mineral particles (sand, silt, and clay), organic matter, and numerous species of living organisms. Soil has biological, chemical, and physical properties that are always changing.

Soil productivity index numbers are based upon the productivity of the soil. They are derived from the mean annual yield that these soil types produce over a 10 year period with moderately managed crops.
