“…The reason behind this may be due to Potassium, which has a significant role in plant nutrition and photosynthesis and raising the efficiency of the plant in absorbing nutrients, especially Nitrogen and phosphorous. Then, ensuring the nutritional balance process, which is positively reflected in improving plant growth and increasing its productivity 6 , These results agree with the findings of (21).…”

“…The results of Table (6) showed that the addition of organic fertilizer led to a significant increase in the nitrogen concentration in the leaves, which reached 4.68% and 4.33% for the two treatments, M2 and 3M (5 and 10% of the size of the terrace) compared to the unfertilized treatment M0 which amounted to 3.64% and an increase of (57.28). The reason for the superiority of organic fertilizer in increasing the percentage of Nitrogen in the leaves may be attributed to the fact that the organic fertilizer contains important stores of Nitrogen, phosphorous, Potassium and iron, as the use of organic fertilizers leads to an increase in the readiness of these elements (Fe, K, P, N) in the leaves.…”

A field experiment was carried out in the agricultural season 2021-2022 in one of the agricultural fields in the Muqdadiya, Al-Harouniya district, located 40 km northeast of the Baquba district of Diyala governorate. The agrarian soil was classified as silty clay (Soil Survey Staff, 2006). It is located at a longitude of 53° 34’ N and latitude of 56° 04° 45° S. The experiment aimed to study the effect of adding chemical and organic fertilizers and spraying seaweed extracts on NPKS concentrations and cauliflower yield. The investigation included three factors: adding organic fertilizer (buffalo waste) at three levels (0, 5 and 10)% of the terrace’s size, symbolized by M1, M2 and 3M, respectively. It was added at a depth of 0-30 cm a month before planting the seedlings in the field. The second factor was the addition of NPK compound chemical fertilizer (20:20:20) at two levels (0 and the full fertilizer recommendation is 300 kg H-1 when planted as a feed) and symbolized by 1 C and 2 C, respectively. The third factor is spraying seaweed extract with three levels (0, 2 and 4) ml L-1 illustrated by A1, A2 and according to an RCBD randomized complete block design with three replications. The experiment results showed that adding organic fertilizer (10% of the size of the terrace) led to a significant increase in the head’s weight, reaching 1.611 kg. The results of the experiment showed that the addition of organic fertilizer (10% of the size of the terrace) led to a significant increase in the weight of the head, as it reached 1.611 kg plant-1, the sulfur concentration in the fruits was 2.00 mg sulfur kg-1, the nitrogen concentration in the leaves was 4.68%. The phosphorous concentration in the leaves was 25%, and the potassium concentration in the leaves was 2.05%; chemical fertilization also increased head weight from 1.385 kg. Plant-1 to 1,108 kg Plant-1.There was an increase in each of the sulfur concentrations in fruits from 2.00% to 1.53%, in the nitrogen concentration in the leaves from 4.60% to 3.48% and an increase in the phosphorous concentration in the leaves from 0.37% to 0.26% and an increase in the potassium concentration in the leaves from 2.78% to 2.27 %, spraying seaweed extracts at a concentration of 4 mmol. L-1 led to a significant increase in head weight, which reached 1.282 kg. Plant-1, nitrogen concentration in leaves 803% and potassium concentration in leaves 2.58%.As for the triple interaction .Keywords: chemical fertilization, organic fertilization, seaweed extracts, cauliflower.

“…The average concentrations of available P and K in the farmland soil reached 3.1 times and 6.3 times those, respectively, in the forest soil, respectively, whereas that of N was 1.9 times that in the farmland soil (Table 1). The extremely high K might result in the positive effects of potassium fertilization on the cassava yields, including the increases in the number and diameter of roots 17 . However, the elevated P:N and K:N ratios in soil may result in excess fertility of P and/or K for cassava plants, and more studies are needed to clarify the imbalance of nutrients in the farmland soil.…”

“…Cassava extracts signi cantly less nitrogen and phosphorus from the soil than most other crops while extracting similar amounts of potassium (K) 12 . Consequently, additional fertilization is needed to maintain soil fertility, when cassava is continuously cultivated on the same land, especially K 13,[15][16][17][18] , phosphorus 18-20 , and nitrogen 19 , possibly leading to the overuse of fertilizers and an imbalance of nutrient levels within the farmland soil 21 . In terms of above-ground environmental factors, including air temperature, solar radiation, and precipitation in Northeast Thailand, the potential production of cassava can be further increased by adopting adequate water management, especially through managing and expanding agricultural land in the mid-highlands 22 .…”

In a national park in Northeast Thailand, agricultural land has been converted from natural forest by small-scale farmers. To investigate the impact of repeated cassava monoculture on soil, we conducted a five-year (2016–2020) study on the physical and chemical properties of soil in cassava farmland and examined the properties of forest soil as a control. Soil nitrogen, available phosphate and potassium, and bulk density were significantly higher in the farmland than in the forest, whereas organic matter and cation exchange capacity were the opposite. In the farmland, soil nitrogen, electrical conductivity, and bulk density increased significantly, whereas pH and organic matter decreased significantly, indicating that soil degradation progressed during the five years. The use of glyphosate and paraquat herbicides is prohibited within national parks. However, in 2020, glyphosate was detected in farmland soil at levels of up to 5.0 mg kg-1 during both the rainy and dry seasons, and glyphosate (2.5 mg l-1) was detected in stream water from the farmland during the dry season. The use of glyphosate in the farmland was suspected at least in 2020. Soil degradation and herbicide pollution may carry a high risk of causing irreversible changes to the terrestrial ecosystems.
