AGRICULTURE AND SOILS Objectives The main objective of the land studies is to derive estimates of land surface biochemical (chlorophyll content) and biophysical (LAI/biomass, albedo, fAPAR) properties by inverting semi-empirical and physically based BRDF models against sample sets of hyperspectral directional reflectance measurements acquired by CHRIS. In addition to specific BRDF studies, the hyperspectral data will also be used to investigate 'red edge' shifts in wavelength as a function of canopy biochemistry (chlorophyll content/concentration). One can consider some advantages and disadvantages of three different types of BRDF model: Physically based based on approximations to radiative-transfer equations computationally intensive numerical inversion techniques sensitive to initial estimates of model parameters Empirical computationally simple poor extrapolation beyond solar and sensor angles for which reflectance data are available Semi-Empirical computationally efficient analytical solutions to model inversion using matrix-based techniques scale linearly The overall aim is to assess the ability of multi-angle reflectance data sampled using the CHRIS sensor to retrieve/estimate land surface biophysical properties (LAI, albedo etc). An element of this will include direct comparison of the retrieved parameter values against ground-based measurements of the same parameters. The surface biophysical parameters will be estimated from the CHRIS data using a number of different techniques, ranging from traditional (the so-called vegetation indices), through more recent developments (such as red-edge position (REP), to more advanced techniques (notably BRDF model inversion). The validation exercise will look at the accuracy/precision with which atmospherically-corrected CHRIS data can be used to determine the basic surface radiation fields, as well as at the ability to retrieve properties such as LAI, albedo, etc. through the application of vegetation indices, REP techniques and BRDF model inversion.

4. National Remote Sensing Agency - Agriculture And Soils Agriculture and Soils. Agriculture. India is an agricultureintensivecountry, and in this scenario, a technology like remote sensing http://www.nrsa.gov.in/engnrsa/spacesolutions/agriculture/

Home Space Solutions Agriculture and Soils Agriculture India is an agriculture-intensive country, and in this scenario, a technology like remote sensing can provide timely and reliable information on agriculture with respect to potentials and limitations of the soil, spatial extention of crops grown and pre-harvesting yield of major crops, which is a pre-requisite for optimal land use planning and formulating policies on food security. Forecasting the yield of mono and multiple crops is being done at NRSA. Acreage estimates and crop inventory is being done during Kharif and Rabi seasons forRice, which is the major crop grown in our country. Other crops like Banana, Chillies, Cotton, Maize, Sugarcane and Tobacco are also being inventoried. Satellite data can also delineate different crops that are grownin the same area, and an inventory of each of the crops can be done. This study is aided by sensors such as IRS WiFS/LISS-III/PAN and Radarsat ScanSAR. Some of the other studies include: Crop condition assessment Agricultural drought assessment Pests and diseases Land capability and irrigability Soils Mapping and monitoring of soil resources is one of the major prerequisites for estimating land capability and irrigability by assessing salt-affected soils, eroded lands,shifting cultivation, etc. For careful land use planning, water-logged areas have to be delineated in order to take up preventive and reclamative measures. Thisrequires dynamic assessment of the salinity/alkalinity content of the soil. These studies are taken up using IRS LISS-III and PAN data.

The original group name "Mulch-based Agriculture" (MBA) was changed to "Management of Organic Inputs in Soils of the Tropics" (MOIST) in order to reflect the group's wider interest in optimizing the management of organic inputs for harnessing the biological potential of legumes, manures, residues, and soil fauna to improve and sustain evolving agricultural systems in Asia, Africa and Latin America. MOIST coordinates development of the TropSCORE Consortium's Worldwide Portal to Information on Soil Health Cover Crop Listserv Archives (Mulch-L, Evecs-L, Coberagri-L)

What is Soil? Soil Formation Soil Classification Soil Physics ... Soil Management In Saskatchewan , agriculture land covers about 40% of the province. According to the 2001 census, 38 million acres (15.4 million hectares) were cropped and 7.7 million acres (3.1 million hectares) were left in summerfallow. Most of the soils have developed over the ten thousand years since the last glaciers retreated. But it is only in the last hundred years or so that these soils have been cultivated by man. Early settlers were given custody of some of the most fertile grassland soils in the world. In a century of soil management, our record has not been good. From the devastation of the "dirty thirties" through the overuse of summerfallow and monocropping to modern day pollution problems with fertilizers and pesticides, we seem intent on abusing one of the most valuable natural resources we have. What is a Soil? Why is soil important? What is it made of? Learn how we study soil through the traditional sciences of physics, chemistry and biology, but with a practical emphasis.
