The Arabian Peninsula is an arid zone with a hot desert climate and severe water scarcity. The low humidity, elevated ambient temperatures, and high evaporation rates in the region deemed conventional surface irrigation unsustainable. The IoT-based subsurface smart irrigation systems can be essentially developed for these regions to avoid surface evaporation losses. In this research, the sandy soil conditions of western Saudi Arabia have been considered in numerical simulations to evaluate the performance of a subsurface smart irrigation system. The influence zone of saturation generated by subsurface diffusers in the target root region has been analysed for two different types of sandy soils. The simulation results generated by the COMSOL Multiphysics program reveal that the subsurface smart irrigation system can be effectively applied to simultaneously manage the target root zone at the ideal saturated conditions and prevent surface evaporation losses.

Micro Irrigation

In agricultural field, irrigation is one of the most interesting considerations affecting the rate of plant growth and development. Micro-irrigation as the dripping or sprinkle method is one of the irrigation types that applies the small amount of water for fulfilling the humidity requirement. The most important factors affecting the demand of water for plants are soil conditions and effect of climatic factors. With less human labour required, to improve the irrigation method from the recent days, analyzing water used or water permeation automatically through the soil moisture has been raised as the interesting topic. Proposed in this research is the ring irrigation system (RIS) which is introduced as an alternative channel for emitters that drip water directly onto the soil at the plant’s root zone where the soil conditions before and after watering can be quickly detected by the sensors. This RIS can be used for the potted plant, green house, or other small farm fields. Product design and development (PDD) is applied in this research for assisting the designer to understand and create the RIS prototype properly according to the customer’s requirements where the suggested functions obtained will be added and tested.

  The agricultural lands are being affected due to groundwater (GW) quality issues. To address this worldwide problematic situation, various irrigation studies have been practiced to identify the effects on the soil conditions. The current study has been designed to assess the GW quality and soil salinity/sodicity by different irrigation techniques in the remote mountainous area of Jamshoro district at Gul Muhammad Khaskheli farm Thana Boula Khan. The experimental plot was designed under furrow, pitcher and poly ethylene bag irrigation system. These soil characteristics indicated that the drain-ability of the soil was high, with an infiltration rate of 1.60 cm/h and water holding capacity was low. Water samples were collected at each irrigation time from sowing to harvest. The soil understudy was non-saline (ECe < 4.0 dS/m) and non-sodic (pH < 8.0, SAR < 7.5 and ESP < 15.0) before crop sowing in all the three methods of irrigation at all the three sampling depths, i.e., 0-15 cm, 15-30 cm and 30-60 cm. Thus, the quality of water used for cultivation of ladyfinger/Okra crop under all irrigation methods was Class-I quality water.The investigated results shown that ECw (electrical conductivity of water) was < 1.5 dS/m, pH < 8.0, SAR (sodium adsorption ratio) < 10.0 and RSC (residual sodium carbonate) were non detective. After crop harvest changed a little bit, change was observed in the soil, i.e., under furrow and pitcher irrigation method, the ECe, SAR. and ESP (exchangeable sodium percentage) decreased in the wetted zone and increased at the wetted periphery. Under the polyethylene bag irrigation method, ECe, SAR and ESP decreased at depths 0-15 cm and 15-30 cm but these increased at lower depth, i.e., 30-60 cm after crop harvest. However, the soil remained non-saline and non-sodic.

Nitrate Concentrations

Abstract Controlled subsurface drainage irrigation systems promote crop productivity; however, these land management systems also allow an efficient pathway for the transport of elements from soils to surface water resources. The nitrate and macro-element effluent concentrations from tile-drainage involving a 40 ha controlled subsurface drainage irrigation system are described and compared to soil nitrate availability. Soil nitrate concentrations generally show an increase immediately after soil nitrogen fertilization practices and are sufficiently abundant to promote their transport from the soil resource to the tile-drain effluent waters. The data indicates that: (1) the transport of nitrate-N in tile-drain effluent waters is appreciable; (2) denitrification pathways effectively reduce a portion of the soil nitrate-N when the controlled drainage system establishes winter-early spring anoxic soil conditions, and (3) the best strategy for reducing nitrate-N concentrations in tile-drain effluent waters is adjusting N fertilization rates and the timing of their application. The development of bioreactors for simulating wetland conditions may further limit nitrate concentrations in surface waters because of soil drainage.

Day By Day

The biggest responsibility of agriculture department is to produce food and cloth for huge population using the resource getting limited day by day. Water scarcity is most threatening among these limiting factors. New techniques are being developed day by day to utilize the water efficiently. Application of water only in the plant root zone will be one of the water saving technique to grow crops. This will control the losses due to evaporation and leaching. Irrigation to soil does not control the climate variables and precipitation cannot be substituted to irrigation. Sprinkler irrigation could be one of the way to utilize the water efficiently by in time application and reducing the losses of leaching and evaporation along with amelioration of micro climate of the crop. Canals and tube well water is conventionally given to crop through flood irrigation. These fields are in direct threat of evaporation and leaching resulting in excess water losses and damaging the soil quality. The study was designed taking cotton as experimental crop to calculate comparisons in plant growth parameters and yields along with water saving ability of different irrigation system. Maximum yield was obtained from sprinkler irrigation and water was saved under drip irrigation system.

The Cost

Traditional methods of irrigation and fertilizing is very time consuming for farmers. Over-irrigation as well as leaching of fertilizers below the root zone, erosion, and transport of soil and chemical particles to the drainage ditches can increase energy and water consumption in farming. A single systems combining irrigation and fertilizing will greatly reduce the cost and time needed in farming. There are two types of fertilizers available for home gardener – granular and water-soluble fertilizers. Generally, granular fertilizers release nutrient gradually but can last longer than water-soluble fertilizers. This project will provide an automated system for irrigation and fertilizing for plantation using Arduino as the microcontroller. This system will include a mobile application to control the amount of water during the irrigation and fertilizing processes. The microcontroller communicates with the mobile application via internet using the Wi-Fi modulator. Then, the microcontroller processes the information and operates the irrigation and fertilizing pumps which supplies water and fertilizer through the sprinkler system in the field. Any feedback will be sent to the user through the mobile application.

SUMMARYA comparison has been made of drip and conventional check basin methods of irrigation, using onions and ladies finger as test crops. Significant increases in yield and water use efficiency in drip irrigated over conventionally irrigated plots resulted from increased availability of soil moisture at low tensions and reduced surface evaporation losses. Reduced soil strength in drip irrigated plots was also a factor resulting in increased yield of onions.

Bioavailable Fraction

Nickel (Ni) bioavailable fraction in the soil is of utmost importance because of its involvement in plant growth and environmental feedbacks. High concentrations of Ni in the soil environment, especially in the root zone, may retard plant growth that ultimately results in reduced plant biomass and yield. However, endophytic microorganisms have great potential to reduce the toxicity of Ni, especially when applied together with zeolite. The present research work was conducted to evaluate the potential effects of an endophytic bacterium Caulobacter sp. MN13 in combination with zeolite on the physiology, growth, quality, and yield of sesame plant under normal and Ni stressed soil conditions through possible reduction of Ni uptake. Surface sterilized sesame seeds were sown in pots filled with artificially Ni contaminated soil amended with zeolite. Results revealed that plant agronomic attributes such as shoot root dry weight, total number of pods, and 1000-grains weight were increased by 41, 45, 54, and 65%, respectively, over control treatment, with combined application of bacteria and zeolite in Ni contaminated soil. In comparison to control, the gaseous exchange parameters (CO2 assimilation rate, transpiration rate, stomatal- sub-stomatal conductance, chlorophyll content, and vapor pressure) were significantly enhanced by co-application of bacteria and zeolite ranging from 20 to 49% under Ni stress. Moreover, the combined utilization of bacteria and zeolite considerably improved water relations of sesame plant, in terms of relative water content (RWC) and relative membrane permeability (RMP) along with improvement in biochemical components (protein, ash, crude fiber, fat), and micronutrients in normal as well as in Ni contaminated soil. Moreover, the same treatment modulated the Ni-stress in plants through improvement in antioxidant enzymes (AEs) activities along with improved Ni concentration in the soil and different plant tissues. Correlation and principal component analysis (PCA) further revealed that combined application of metal-tolerant bacterium Caulobacter sp. MN13 and zeolite is the most influential strategy in alleviating Ni-induced stress and subsequent improvement in growth, yield, and physio-biochemical attributes of sesame plant.
