“…Based on the critical water resource situation in the dry-land farming area of China, an improvement in the WUE through fertilizer management is an urgent and crucial need [29]. A major factor restricting WUE in semiarid regions is the vertical distribution of soil water under limited precipitation, as precipitation is the only water resource that replenishes deeper soil water [17,30]. In present study, topsoil structure and rain water infiltration into the deeper soil profile of 0.5-1.5 m were improved under organic manure input, as evidenced by the stable SWC in the 0-0.5 m and below the 1.5 m soil layer and the SWC decrease in the 1.0-1.5 m soil layer (Figs 5 and 6).…”

Long-term chemical fertilizer input causes soil organic matter losses, structural compaction, and changes in soil water and nutrient availability, which have been subdued in the most of dry farmland in China. The concept of "more efficiency with less fertilizer input" has been proposed and is urgently needed in current agriculture. Application of chemical fertilizer combined with organic manure (OM) could be a solution for soil protection and sustainable production of dry-land maize (Zea mays. L). Field research over three consecutive years on the Loess Plateau of China was conducted to evaluate the integrated effects of chemical fertilizer strategies and additional OM input on soil nutrients availability and water use in maize. The results showed that, after harvest, soil bulk density decreased significantly with OM application, concomitant with 11.9, 18.7 and 97.8% increases in topsoil total nitrogen, organic matter, and available phosphorus contents, respectively, compared with those under equal chemical NPK input. Water use in the 1.0-1.5 m soil profile was improved, therefore, the soil conditions were better for maize root growth, leaf area and shoot biomass of individual maize plants increased significantly with OM application. Optimized NPK strategies increased grain yield and water use efficiency by 18.5 and 20.6%, respectively, compared to only chemical NP input. Furthermore, additional OM input promoted yield and water use efficiency by 8.9 and 5.8%, respectively. Addition of OM promotes sustainable soil and maize grain productivity as well as friendly soil environmental management of dry land farming.

“…Potassium deficiency in soils can be alleviated by potassium fertilizers, but the fact that potassium is an essential nutrient element for plants has promoted the production of potassium fertilizers worldwide, with commensurate rises in price. More expensive fertilizers accordingly lead to higher crop production costs that reduce farmers' profitability [58]. To overcome these limitations, a solution that transforms unavailable potassium into a usable form must be an alternative [59,60].…”

Effects of Potassium Deficiency on the Growth of Tea (Camelia sinensis) and Strategies for Optimizing Potassium Levels in Soil: A Critical Review

et al. 2022

Potassium is among the three essential macronutrients for tea plants, along with nitrogen and phosphorous, and plays important roles in growth and stress response. Potassium is absorbed by plants in larger amounts than any other mineral element except nitrogen and, in some cases, calcium. At present, more than 59% of China’s tea gardens are in a state of potassium deficiency, which negatively affects tea quality and yield. This paper reviews the effects of potassium deficiency on tea plant growth and stress response, details factors affecting potassium supply and demand in tea gardens, examines the interactions between potassium and other elements in soils, and provides strategies for optimizing potassium levels in soils. Potassium is positively correlated with the elements nitrogen, copper, and zinc. Sufficient potassium dramatically improves the yield and quality of tea: it accelerates metabolism, promotes synthesis of catechins, and strengthens biotic and abiotic resistance by activating and regulating different enzymes. Moderate application of potassium fertilizers, along with potassium-solubilizing bacteria, can regulate the ratio of different forms of potassium and increase available potassium in soils of tea gardens. We suggest that research on potassium occurring in soils and its interaction with other elements be strengthened, so as to improve the efficient use of potassium fertilizers in tea gardens and maintain the balance of elements in soils.

“…The addition of crop residue, which contains a significant amount of K, to the soil was not practiced by farmers, thus worsening the K depletion status across the soil [12,13]. As a crucial nutrient, rising demands for K for agricultural crop growth may spur global K fertilizer output in response to rising synthetic fertilizer demand [14]. An alternate indigenous supply of K is desirable for optimum plant uptake in order to combat these constraints and retain the K status available in the soils to support crop production [15,16].…”

Polyphasic Characterization of Indigenous Potassium-Solubilizing Bacteria and Its Efficacy Studies on Maize

Potassium (K) helps crop plants to resist biotic and abiotic challenges and plays a vital role in biochemical, metabolic, and physiological processes. Due to intense agricultural practices over the past few decades, the soil K reserve has been observed to be decreasing globally. It is possible to view potassium-solubilizing bacteria (KSB), which uses a number of biological mechanisms to convert potassium from inaccessible forms and make it accessible to crop plants, as a viable method for managing K in soils with low potassium levels. The present study encompasses 44 KSB strains isolated from rhizospheric soils collected from southern Rajasthan, India and characterized based on morphological, biochemical, and molecular profiles. All the isolates exhibited potassium solubilization and were identified using ERIC, BOX, REP PCR, and 16 S rDNA amplification which exhibited significant diversity amongst the strains. A flame-photometric analysis revealed that significant amounts of potassium were released by isolates from muscovite mica on the 21st day of incubation. These KSB strains produced hydrolytic enzymes and plant growth-promoting activities at different environmental stresses. In comparison to the absolute control (control without KSB), maize seedlings grown from bacterized seeds showed an increase in shoot length, root length, leaf number, total chlorophyll content, and the expression of stress-related enzymes. These native strains, which have a variety of advantageous traits, may be able to replace synthetic K fertilizers in order to increase food production while reducing pollution and restoring degraded land for agricultural use.
