What Is limited irrigation?
When water supplies are restricted, so that full evapotranspiration demands cannot be met, limited irrigation results. Limited irrigation management are practices that incorporate crop rotations, water management during the vegetative…
Leaching Requirement (LR)
The avocado is the most salt sensitive fruit tree. In order to maintain acceptable yields it is necessary to leach the soil of salts deposited mainly by the irrigation water.…
Leaching of soil
The soil in your garden is like a sponge. When rain falls, the soil near the top absorbs as much as possible, keeping the moisture available to the plants growing…
Water Application Uniformity
There are other ways to assess the uniformity of irrigation. For example, look at the crop and the uniformity of growth, especially perpendicular to the irrigation sprinkler head. If, after…
Infiltration
What it is: Infiltration is the downward entry of water into the soil. The velocity at which water enters the soil is infiltration rate. Infiltration rate is typically expressed in inches…
THE CONCEPT OF SOIL ADSORPTION AND DESORPTION
When organic compounds come into contact with soils and sediments they can be taken up by organisms, be degraded by biotic and abiotic mechanisms or transported within the aqueous phase (sediments)…
Different Types of Soil Water
Soil water is the term for water found in naturally occurring soil. Soil water is also called rhizic water. There are three main types of soil water - gravitational water,…
Field measurements
The evaluation of surface irrigation at the field level is an important aspect of both management and design. Field measurements are necessary to characterize the irrigation system in terms of…
Evapotranspiration
Have you ever heard someone mention "ET" and wondered what it meant? Assuming the person wasn’t talking about extra-terrestrials or Entertainment Tonight, the conversation was probably about evapotranspiration. Evapotranspiration (or "ET")…
Deep Percolation
Deep percolation (DP) from irrigation may be important for groundwater recharge in arid region irrigated agricultural river corridors, yet few studies in this physiographic setting have characterized both percolation and…
