“…Soil moisture content declined as the lateral distance from the emitter increased [32]. The soil moisture distribution changed quickly after watering as water moved rapidly through the soil and then slowed down [32]. In the current study, soil moisture decreased as the horizontal distance increased from the emitter point.…”

Agricultural soils are a primary source of greenhouse gas (GHG) emissions. Biochar is commonly used as a soil amendment to prevent climate change by reducing GHG production, increasing soil carbon storage, improving soil moisture retention, and enhancing crop productivity. However, the impact of biochar’s carbon content under subsurface drip irrigation (SDI) has not been well studied. Here, we investigated the effect of different carbon (C) contents in wheat biochar under different SDI depths on soil nitrous oxide (N2O), carbon dioxide (CO2), soil moisture distribution, and Pakchoi productivity. A pot experiment was conducted using three SDI depths, emitters buried at 0.05, 0.10, and 0.15 m below the soil’s surface, and three levels of C content named zero biochar (CK), 50% C (low (L)), and 95% C (high (H)) in greenhouse cultivation. The findings showed biochar significantly decreased N2O and CO2 emissions. Compared to CK, the L and H treatments decreased N2O by (18.20, 28.14%), (16.65, 17.51%), and 11.05, 18.65%) under SDI5, SDI10, and SDI15, respectively. Similarly, the L and H treatments decreased CO2 by (8.05, 31.46%), (6.96, 28.88%), and (2.97, 7.89%) under SDI5, SDI10, and SDI15, respectively. Compared to CK, L and H increased soil moisture content. All plant growth parameters and yield traits were enhanced under SDI5. In summary, biochar addition significantly decreased soil N2O and CO2 emissions compared to CK, and increased growth performance and yield, and maintained soil moisture content. The H treatment significantly reduced N2O and CO2 emissions, increased plant growth and yield, and maintained soil moisture content compared to the L treatment. Soil moisture was reduced vertically and horizontally with increased radial distance from the emitter.

Functional Design of Pocket Fertigation under Specific Microclimate and Irrigation Rates: A Preliminary Study

et al. 2022

Irrigation and fertilization technologies need to be adapted to climate change and provided as effectively and efficiently as possible. The current study proposed pocket fertigation, an innovative new idea in providing irrigation water and fertilization by using a porous material in the form of a ring/disc inserted surrounding the plant’s roots as an irrigation emitter equipped with a “pocket”/bag for storing fertilizer. The objective was to evaluate the functional design of pocket fertigation in the specific micro-climate inside the screenhouse with a combination of emitter designs and irrigation rates. The technology was implemented on an experimental field at a lab-scale melon (Cucumis melo L.) cultivation from 23 August to 25 October 2021 in one planting season. The technology was tested at six treatments of a combination of three emitter designs and two irrigation rates. The emitter design consisted of an emitter with textile coating (PT), without coating (PW), and without emitter as a control (PC). Irrigation rates were supplied at one times the evaporation rate (E) and 1.2 times the evaporation rate (1.2E). The pocket fertigation was well implemented in a combination of emitter designs and irrigation rates (PT-E, PW-E, PT-1.2E, and PW-1.2E). The proposed technology increased the averages of fruit weight and water productivity by 6.20 and 7.88%, respectively, compared to the control (PC-E and PC-1.2E). Meanwhile, the optimum emitter design of pocket fertigation was without coating (PW). It increased by 13.36% of fruit weight and 14.71% of water productivity. Thus, pocket fertigation has good prospects in the future. For further planning, the proposed technology should be implemented at the field scale.

“…It is important not to skip the critical stages of irrigation when cabbage seedlings have 6-7 leaves and at the beginning of head formation (Bute et al, 2021). Hamad et al (2022) stated that cabbage producers often use high amounts of nutrients and water to increase yields. Excessive irrigation and application of N-fertilizers can lead to environmental problems, including greenhouse gas emissions.…”

Cabbage is one of the most commonly produced vegetable crops worldwide due to its ability to adapt to a range of climatic conditions and soil types. As an intensive vegetable crop, cabbage can be produced all year round. Regarding the fact that cabbage needs optimum agroclimatic conditions during growing period for better yielding results, the paper aims to clarify and define the specific agroclimatic requirements, such as temperature, water, light and soil, suitable for cabbage production. Cabbage production should take place on a seasonal basis, as an early, summer, autumn, or winter production. Production goals should take into consideration whether the cabbage is intended for fresh consumption, pickling, storage or another specific method of consumption or processing. Growing the same cultivar in two different temperatures during one year should be avoided. The combination of suitable production conditions, intensive cultivation practices and mechanisation, can boost the genetic potential of the cabbage cultivars. Local climate conditions greatly affect cabbage production, primarily plant growth, occurrence and development of diseases, harmful insects, and weeds. Production planning must take into consideration both the regional (mean annual temperatures and precipitation) and the local climate conditions (frost occurrence). Cabbage is currently produced in the open field throughout the year, but we may be forced to change the course of cabbage production due to the increase of extreme local climate change. For this reason, the aim of this paper was to give recommendations of agricultural practices that could minimize the detrimental effects of climate change in cabbage production.
