Properties of Polymer in Agriculture

Viscoelastic property Combination of

Viscosity

Elastic

Response

VE• under mechanical stress, of materials which are intermediate

between liquids and solids

VE• It depends upon Temperature and pressure

PolymersUsed as basic material in soil conditioners etc., which is very important in

Agriculture

Pharmaceutical industry

Bio-technology

Textile industry

Automobile industry

Petroleum industry

Transmission

Stability

Permeability

Principal requirements for a polymer

Permeability

Permeation is the rate a which a gas or vapor passes

through a polymeric material.

TRANSMISSION

Polymer- water vapor transmission

Polymer-soil surface

transmission

Inter layer transmission

STABILITY

Polymer Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.

Stability is nothing but how polymer can withstand.

POLYMERIC BIOCIDESAspects

It allows lower amounts than conventional biocides

It releases required amount of active agent over a long period

Reduction of toxicity

Reduction of evaporation and degradation

MolluscicidesThe use of molluscicides is to combat various mollusks,

the applications of large quantities of these Chemicals are required

Chemical combination of Molluscicides with functionalized polymers

Enhancing the eradication of snails

Polymeric soil conditioners The polymers were developed to improve the physical properties of soil in view of:

increasing their water-holding capacity increasing water use efficiency enhancing soil permeability and infiltration rates reducing irrigation frequency reducing compaction tendency stopping erosion and water run-off increasing plant performance (especially in structure-less soils

in areas subject to drought).

Bio degradable polymers

Increasingly used as Plastics substitutes for several applications in agricultural field

Bio-degradable polymers disposed in bioactive environment

Conventional polymers, Polyethylene and Poly-propylene persist for many years after disposal

Polymers in Agro-chemical

It supports Herbicides overcome the serious environmental problems of the

conventional herbicides

Polymers in Heavy metal Removing

Major Problem in Agriculture Is Soil Pollution due to Heavy metals

The soil is long term sink for the group of toxic elements(heavy metals)

Say Zinc, copper, Nickel, Lead, Chromium, Cadmium
