“…Rosenzweig et al (2002) reported that, in the Midwestern USA, agricultural production damages that are related to excess soil moisture, i.e., a lack of agricultural drainage, can be up to five times higher than the direct damages due to crop submersion by floods. Moreover, ditches, as the collectors of tile drainage systems, also play a role in other subsurface drainage functions, e.g., soil salinity control (Christen et al 2001;Ritzema et al 2008) especially in irrigated areas. Finally, D'Itri and Belcher (1994) also mentioned that field drainage associated with water level regulation in ditches controls the minimum water table level during the dry season for crop subirrigation.…”

Agriculture must now feed the planet with the lowest environmental impact. Landscape management is a means to protect natural resources from the adverse impacts. In particular, the adequate management of ditches could improve crop quality. Here, we review ditch design and maintenance. We found the following major points: (1) ditch networks have been primarily designed for waterlogging control and erosion prevention. Nonetheless, when properly managed, farm ditches provide other important ecosystem services, namely groundwater recharge, flood attenuation, water purification, or biodiversity conservation. (2) All ditch ecosystem services depend on many geochemical, geophysical, and biological processes, whose occurrence and intensity vary largely with ditch characteristics. (3) The major ruling characteristics are vegetative cover; ditch morphology; slope orientation; reach connections such as piped sections and weirs, soil, sediment and litter properties, biota, and biofilms; and network topology. (4) Ditch maintenance is an efficient engineering tool to optimize ecosystem services because several ditch characteristics change widely with ditch maintenance. For instance, maintenance operations, dredging, chemical weeding, and burning improve waterlogging and soil erosion control, but they are negative for biodiversity conservation. Mowing has low adverse effects on biodiversity conservation and water purification when mowing is performed at an adequate season. The effects of burning have been poorly investigated.

“…The amount of exchangeable sodium (exNa), measured in me/100g, is an important factor determining a soil's suitability for supporting plants [45] as it strongly influences water infiltration and soil aeration. Furthermore, soils of arid and semi-arid areas contain large quantities of sodium (Na), and irrigation agriculture in such areas is often a source of soluble salts even if excellent quality water is used [40]. Excesses of exNa (>2.5%) becomes toxic to the plant, and affects plant growth since it adversely alters the physical and chemical conditions of the soil (i.e., soil permeability, dispersion [40] and water permeability).…”

Greenhouse commercial horticulture in Kenya started more than two decades ago and has evolved to be a significant sector to the national economy. So far no studies have explored the spatial patterns and dynamics of the area under greenhouse cultivation. Google Earth archives alongside data from various portals provided an opportunity to study those farms' spatial distribution. The roles of selected topo-edaphic, infrastructure and demographics factors that might influence current location within sub-watersheds in central highlands of Kenya are also examined. Results reveal a non-uniform spread with two high clusters; one in the semi-arid sub-watersheds 3AB shared by Kajiado and Machakos districts and the other is in sub-humid sub-watersheds 3BA shared by Kiambu and Nairobi districts. Multivariate linear regression analysis reveals four statistically significant parameters; population density (p < 0.01), number of dams (p < 0.01), average rainfall (p < 0.01) and average slope (p < 0.05) in predicting the number of greenhouse farms. Soil attributes are not significantly related with greenhouse farming in this study. Findings indicate that greenhouse commercial horticulture is heterogeneous, and rapidly expanding beyond the central highlands towards marginal semi-arid zones in Kenya. These findings are applicable in policy and decision making processes that aid the horticulture sector's progress in a sustainable manner.

“…The primary practice preventing soil salinization involves accelerating of the downward movement of salt and leaching salt ions from the cultivation layer via a given column of water irrigation; another method involves reducing the content of salt ions by burying pipes below the cultivation layer [6]. Those approaches can effectively reduce the topsoil salt content, but is financially costly and labor intense [7].…”

A hydroponic experiment was carried out to investigate the effects of magnetic water irrigation on the growth, nutritional status and antioxidant enzyme activity of cotton seedlings. Four levels of magnetic-treated water irrigation (0, 100, 300 and 500 mT) and three levels of salt stress (0, 100 and 200 mM NaCl) were applied. Salt stress adversely affected the dry weight, nutrient uptake and antioxidant enzyme activities of cotton seedlings. Magnetic-treated water irrigation significantly increased cotton seedling dry weight. Cotton seedling dry weight increased by 14%, 22% and 29% under the treatments of 100, 300 and 500 mT magnetic water irrigation, respectively, compared with the control, at a salt stress level of 100 mM NaCl. Moreover, magnetic water irrigation improved N uptake, but did not significantly affect P and K uptake. Magnetic water irrigation significantly increased the activity of superoxide dismutase (SOD), peroxidase (POD) and the proline content compared to the control (0 mT). Irrigation with magnetic water could be a promising technique in agriculture, especially under salt stress conditions. A suitable magnetic intensity of 300 mT is recommended.
