Extraction of potassium from agricultural soil often involves strong acids (HCl, HNO 3 , H 2 SO 4 , HClO 4 , HF), whose decomposition results in formation of toxic gases. Green solvents are environmentally friendly and are used in place of conventional solvents that are hazardous to both human and the environment. Also, potassium in agricultural soils is often incorporated in minerals that are highly insoluble, and thus highly unavailable to plants. Usage of strong acids may result in much higher concentrations of potassium, and a wrong insight into potassium bioavailability. This erroneous result for the potassium content could lead to improper usage of fertilizers. The most important fractions of potassium for plant growth are mobile an easily mobilizable fractions. Those fractions are extracted with water and weak acids. Technique for sample preparation that is often used is shaking and ultrasound assisted extraction. In this research, two green extraction solutions with two different extraction mechanisms and two different soil types were used. All results were compared to pseudo-total amounts of metals. pH, EC, moisture content and Al -solution extracted potassium (available to plants), as basic quality parameters were measured. Potassium content was measured by means of flame atomic emission spectroscopy (FAES). Mobile and easily mobilizable fractions correlate to a high extent (r <0.800), but they are negatively correlated to pseudo-total amounts. Pseudo-total amount gives a wrong insight into the content of potassium available to plants. The ultrasound filed could be used in case of soils that are low in a clay content.

This research aims to determine the effect of a combination of straw compost and chicken manure on the availability of N, P, K nutrients and the growth of sweet corn (Zea mays L.) plants in peat soil. The research was carried out at the experimental garden, Faculty of Agriculture, Tanjungpura University. The research took the form of a field experiment with a Completely Randomized Design (CRD) pattern consisting of 5 treatments and 5 replications, so the total number of treatments was 25 plants. The treatments referred to are: P1: 40 tonnes/ha of rice straw compost (900 g/polybag), P2: 40 tonnes/ha of chicken manure (900 g/polybag), P3: 20 tonnes/ha of rice straw compost + 20 tonnes/ha chicken manure (450 g/polybag + 450 g/polybag), P4: 30 tons/ha rice straw compost + 10 tons/ha chicken manure (600 g/polybag + 300 g/polyag), P5: 10 tons/ha rice straw compost + 30 tons/ha chicken manure (300 g/polybag + 600 g/polybag). Statistical analysis used one-way Anova and DMRT follow-up test. Parameters of soil chemical properties include soil N-total, soil available P, soil K-dd and soil pH. Growth parameters include plant height and stem diameter. The research results showed that the use of chicken manure alone and a combination of chicken manure and rice straw compost could increase P-available, plant height and stem diameter of sweet corn plants in peat soil. The use of rice straw compost alone and a combination of rice straw compost and chicken manure can increase soil pH and soil K-DD. Providing a combination of rice straw compost and chicken manure can increase N-Total, P-Available, Soil K-DD, plant height and stem diameter of sweet corn plants.

“…Humus, potassium, and phosphorus are critical soil components that profoundly impact ecosystem productivity, plant growth, and development. They regulate various processes, including greenhouse gas fluxes, nutrient cycling, infiltration, and water retention (Lehmann et al, 2020;Kassa et al, 2021). Their presence in soils effectively reflects both the dynamic and static changes in soil formation conditions, including those induced by anthropogenic activities like soil contamination.…”

Humus, potassium, and phosphorus are key components of soil that play crucial roles in ecosystem productivity, plant growth, and development. They control a wide range of processes, including greenhouse gas fluxes, nutrient cycling, infiltration, and water retention. This article presents the results of evaluating humus, potassium (K), and phosphorus (P) content in the profile of brown soils in mountain pastures of Uzbekistan, as well as their distribution within these soils. The brown soils studied in the mountain pastures of Uzbekistan have a loamy granulometric composition, with the clay fraction not exceeding 20%. The carbonate content is low (2.5-9%), with the maximum amount found in the carbonate horizon. The soils exhibit weak leaching. The total humus content in the upper horizon varies from 1 to 6.6%. It was observed that the soils on the more moistened northern and western slopes contain more humus than those on the southern and eastern slopes, indicating a dependence of high humus content on slope exposition. For the first time, the article allocates phosphorus and potassium of near, labile, and potential reserves (as a percentage of the total content) to estimate the change in the nature of brown soils under economic use. It was found that the potential reserve of phosphorus and potassium (35.5-90%) prevails in soils. Further study of the features of humus, potassium, and phosphorus, their accumulation, and restoration in brown soils is essential for developing recommendations for the rational use, anti-erosion protection, and increased productivity of mountain pastures in Uzbekistan.
