Irrigation efficiency improvement requires optimization of its parameters like irrigation scheduling, threshold and amount of water usage. If these parameters are not satisfactorily optimized, negat...
Compost leachate is produced by conversion of municipal waste to compost. It contains significant amounts of organic materials, nutrients, soluble salts and small amounts of some heavy metals. Addin...
The efforts to introduce the micro irrigation system in Iran go back as far as the year 1990. The area under micro irrigation system in Iran covers about 400 000 ha and it is estimated to double (800 ...
A central objective in irrigation science is the improvement of the water use efficiency (WUE). Mostly the focus is laid on improvements and innovations in irrigation technology. The characteristics o...
In this study, three mathematical models in the SIRMOD package including the hydrodynamic (HD), zero inertia (ZI), and kinematic wave (KW) models were tested using the data from several field experime...
The present paper focuses on the point irrigation design for crops and growing vegetables on an experimental area 2432 m2 at Buchel locality, Northern part of Gobi desert in Mongolia. An underground w...
This paper presents the results of the nitrates movement monitoring under the conditions of field experiment, with different fertilisation doses applications, with and without irrigation and, for di...
Water is a basic necessity for turfgrass growth and metabolic processes, with optimal levels required for the maintenance of turf quality and function. As water restrictions for irrigation of landscap...
Phosphogypsum (PG) is a by-product of the P fertilizer industry usually valorised as amendment for acidic and sodic soils. This work was aimed to study the effects of PG on nutrient uptake by industri...
This study examined changes in some soil hydrophysical, chemical properties and wheat yield (grain; straw yield, N, P, K, Protein and carbohydrates contents) as trends under two cultivated period 10 a...
The use of treated wastewater (TW) for irrigation is increasingly being considered as a technical solution to minimize soil degradation and to restore nutrient content of soils. Indeed, TW usually con...
Soil fumigant delivery through microirrigation (drip) lines has the potential to replace direct soil injection into planting beds. However, wetting coverage in these Spodosols must be improved to incr...
Rice grows well under certain condition and environment including soil, water and nutrients. Some researches have shown that traditional method with continues flooding need tremendeous amount of water...
In irrigation schemes under rotational water supply in semiarid region, the water allocation and irrigation scheduling are often based on a fixed-area proportionate water depth with every irrigation c...
The aim of this research was determine the en- ergy and water use efficiencies under the modification of closed circuit drip irrigation systems designs. Field experiments carried out on transgenic mai...
