Fertigation-Chemigation are regular and widely accepted practices for fertilization and plant protection under protected agriculture. With fertigation, the nutrients in the form og soluble fertilizers anticipated to most crops needs according to their stage of development, are applied with the irrigation water. The application of plant protectants through irrigation system such as herbicides, fungicides, insecticides, nematicides, growth regulators and bio control agents has been also expanded rapidly during the last few decades.   However, the application of any chemical to soil and crops may have envarionmental implications, in this work crtical thecnical aspects, the current knowladge anf futuer prospects of fertigation-chemigation for crops yield and improve quality on degradation-free and sustainable basis, are presented.

This publication presents in abbreviated form the fertilization recommendations for vegetable crops based on soil tests performed by the IFAS Extension Soil Testing Laboratory (ESTL). It contains the basic information from which ESTL soil-test reports and fertilization recommendations are generated
