A field study was conducted in 2016–2017 and 2017–2018 to evaluate the effects of air injection into an irrigation stream during the subsurface drip irrigation (SDI) process on the nutritional values and productivity of potato grown in clay loam soil. Two irrigation treatments (non-aerated and aerated) and six fertilizer applications (chicken, cow, rabbit, compost, mineral, and chicken + biochar) were compared. In the first growing season, the maximum yield occurred under aerated treatment with cow fertilizer (36.25 ton ha−1), while the minimum yield occurred under non-aerated treatment with chicken fertilizer (24.00 ton ha−1). On the other hand, the maximum and minimum yields in the second growing season were 35.00 and 24.74 ton ha−1 under aerated and non-aerated treatments with cow fertilizer, respectively. Maximum water productivity was achieved under aerated treatment with cow fertilizer (10.04 and 9.13 kg m−3 for the first and second growing seasons, respectively), while minimum water productivity was achieved under the non-aerated treatment with chicken + biochar fertilizer (5.91 and 5.26 kg m−3 for the first and second growing seasons, respectively). Fertilization using aerated treatment yielded the best results and the highest coupling after air injection, compared with the traditional methods of adding soil fertilizer without aeration. The plant growth parameters significantly increased following aeration relative to non-aerated treatments for all fertilizer applications in both growing seasons. Air injection into the soil for potatoes, unsurprisingly, not only benefitted the crop by increasing the soil–air exchange rate but also promoted water infiltration rates and nutrient absorption and reduced drainage water, thus increasing water productivity and reducing the overall irrigation requirements.

Moldboard Plow

A filed experiment has been conducted at college of agriculture research station, Garmit Ali , Basrah university in ( 2014 ) . The soil texture is clay . Three plow types are used namely modifiled subsoiler , conventional subsoiler and moldboard plow . The first two plows (subsoilers) are used at operating depths of 30 , 40 and 50  cm . The moldboard plow is used at operating depth of 25 cm . These plow types are used to study their effect on the soil  water infiltration of the soil in after crop harvesting. The crop used in the experiments is sun flower ( Helianthus annus L.) . The following abbrivations are used for the modified and conventional subsoilers operating depths 30 , 40 , and 50 cm , which are they S1D1 , S1D2 , and S1D3 and S2D1 , S2D2 and S2D3 respectively . For the moldboard plow depth of 25 cm  MT is used and no tillage treatment (NT) . The control treatment is given (con.) . The filed is divided into three equal area blocks . Each block is divided into nine experimental units . The experimental parameters are randomly distributed on experimental units . The crop seeds are planted on 4/4/2014 . The irrigation is added according to the difficiency in the water level of water evaporation basin . The addition of water is 100% of the measured evaporation value with another 20% as leaching requirement . The crop harvesting date is 4/7/2014 .The results showed :That plowing operation reduced Acumulative infiltration and infilteration rate are higher in the plowed soil compared with unplowed soil (NT) . At the end of season growth S1D3 recorded the highest equmilative and mean infiltration while the lowest values are recorded to MT . The rest of treatments gave medium results.

The Impact

Improving soil-water relations by amending soil with biochar might play a significant role in increasing water availability for agricultural crops as well as decreasing water loss through drainage or runoff. While the effects of biochar on the hydrological properties on coarse-textured soils are generally positive and well-documented in the literature, studies on biochar effects on fine-textured soils are rather scarce and even contradictory. Therefore, the aim of this paper was to investigate the impact of biochar on the bulk density, water retention curve (together with several water capacitive indicators) and water infiltration rate in a clay loam soil. A pot experiment was carried out under lab conditions in which biochar was mixed with soil at rates of 0 (B0 or control), 2, 4, 6, 8 and 10% dw (B2, B4, B6, B8 and B10, respectively). Water retention of soil–biochar mixtures at different matrix potentials was determined using a pressure plate apparatus. From these measurements, a series of capacitive indicators was derived and the fitting of the van Genuchten model was also performed. Water infiltration into soil–biochar mixtures was measured by means of a mini-disk infiltrometer and the obtained data were analyzed both directly and by fitting the Philip’s model. Biochar significantly affected the considered soil properties. As the biochar rate increased, the bulk density decreased and water retention increased (B6, B8 and B10 > B2, B4 and B0), while the infiltration rate decreased (B0 > B2, B4, B6, B8 and B10). Although the experiment was performed on sieved and repacked soil samples under lab conditions, the results confirmed that biochar has the potential to increase plant-available water, while possibly reducing drainage water in a clay loam soil by lowering the infiltration rate.
