Principles and Practices of Water Management: Fertigation in Controlled Environments
Fertigation is a cultivation method where complete fertilizer is delivered to crops in solution form through drip irrigation. Basic requirements include greenhouses, drip irrigation systems, clean water supply, pH and EC adjustment tools, and suitable nutrient concentrations. Effective water management in controlled environments and polyhouses is essential for successful fertigation practices.

Course name Principles and Practices of Water Management (AGRO 0504) Course Credit 2+1 Lecture 1 Topic: Fertigation.
Fertigation Fertigation is derived from the word "fertilizer" and irrigation". Fertigation system is a method of cultivation in which the provision of a complete fertilizer to crops is given in the form of a solution and delivered to the root zone through a drip irrigation system.
Management of water in controlled environments and polyhouses. Basic Requirement The basic requirement that are need in fertigation system are: 1.Green House /ploy House : needed to control excess moisture, especially during the rainy season Roof - must allow sunlight to pass through Type of roofing materials - using transparent plastic 2. Irrigation system : Using the drip irrigation system. Function: Flush and distribute or supply water and nutrient rooting zone into each polybeg. 3. Water supply and quality Must use clean water and quality Water quality is important to the success of this system Eg: tap water, pool water, river water pH value and optimum air EC - 6.5 5.5, <1.0 mS / cm 4.Adjust solution tools (pH and EC metre) Use to determine the pH and EC of fertilizer solution and media are in optimum. The concentration of fertilizers and media depend on the plant that we have planted. EC needs a range of 1.2 mS / cm - 3.8 mS / cm BPSP 2014/2015
