“…Research has investigated whether P applied to the soil influences P limitations at a large scale. However, significant uncertainty remains regarding the P found in different forms adsorbed on the soil surface with different elements (i.e., iron (Fe), aluminum (Al), and calcium (Ca)), which differ in their bioavailability, mobility, and behavior in the soil, depending on the pH, parent material, and fertilization background [10,11]. Consequently, it is important to assess the effects of P application on P limitation with different fertilizer rates and different mechanisms.…”

Excessive phosphorus (P) application can alter soil P availability and limit plant growth by compacting soil and fixation of P into different organic and inorganic forms. However, it remains uncertain whether these changes happen after limited fertilization or an excessive rate applied under the winter wheat cropping system. The current study aimed to identify the transformation of P into different organic (Po) and inorganic (Pi) fractions, and their role in the plant P uptake and winter wheat (Triticum aestivum L.) production. A long-term study (12 years) was conducted to assess the changes in soil Pi and Po fractions in response to different P rates (0, 50, 100, 150, and 200 kg P2O5 ha−1) applied to winter wheat. Phosphorus fractions were determined using the Hedley modified Tiessen and Moir fractionation scheme. Our findings demonstrated that different P rates significantly increased the available P, particularly NaHCO3-Pi, in the inorganic P fractions compared to P0 treatment. NaHCO3-Pi showed a strong relationship with grain yield (R2 = 0.91) and P uptake (R2 = 0.80). Grain yield was significantly higher in the P100 treatment, but no significant difference was observed between P100 and P200 treatments. The P200 treatment had a maximum grain P content and plant P uptake. Compared with the P0 treatment, all organic fractions yielded the highest Po with the P rate increase, ranging from 27.3 to 75.6 mg kg−1, 27.2 to 35.6 mg kg−1, and 58.8 to 124 mg kg−1 for NaHCO3-Po, NaOH-Po, and HCl-Po, respectively. Among all Pi fractions, the maximum fraction, known as apatite (HClD-Pi), was found in the P200 treatment with the range of 165 to 245.9 mg kg−1. HClD-Pi accounted for 32% of total P, which can be transformed into the available P form with the passage of time. An increase of 78% in residual P was found under the treatment of P200. The residual P fraction was positively correlated with grain yield, P uptake, and other inorganic fractions. It can be concluded that application of P increases P availability and grain yield with an increase in its application rate, but too much use of P can cause soil pollution and higher fixation of P. Consequently, a balanced application of fertilizer is recommended to reduce its fixation and increase its availability for higher crop yield.

“…It is easy to chemically react with phosphate fertilizers applied to the soil and form sediments and accumulate in the soil, which cannot be used by plants, resulting in generally high soil available phosphorus content ( Liao et al, 2019 ). However, different types of organic fertilizers and soil parent materials have different capacity to fix soil phosphorus, resulting in differences in soil available phosphorus content ( Mehmood et al, 2015 ; Shu, Qi & Wang, 2021 ). Soil nutrient sources, utilization efficiency and their migration in soil are the main factors that determine the spatial variation of soil nutrients ( Sun et al., 2018 ).…”

It is of great significance to promote the quantitative research of soil science and the implementation of precision agriculture. On this basis, taking Xuwen County as the research object, this paper comprehensively analyzed the soil characteristics of cultivated land in Xuwen County and clarify the soil nutrient content and spatial distribution characteristics of cultivated land in Xuwen County, this paper comprehensively applied the methods of geostatistics, geographic information system (GIS) and fuzzy mathematics, and referred to the cultivated land quality grade standard (GB/T 33469-2016), to analyze the soil characteristics and evaluate the soil fertility of this region. The results show that the optimal interpolation model of soil pH and available phosphorus (AP) is a Gaussian model, and the optimal interpolation model of soil organic matter (SOM), available nitrogen (AN) and available potassium (AK) is a J-Bessel model. In addition, the spatial correlation of AK is weak, whereas pH, SOM, AN and AP show moderate spatial correlation. The proportion of excellent, good, average, medium and poor comprehensive fertility index are 26.00%, 32.67%, 19.33%, 19.00% and 3.00%, respectively. The overall level of soil fertility in Xuwen County is above the average, and the fertility quality presents an obvious trend of high in the South and low in the North. Areas that above average fertility are mainly distributed in Maichen Town, Qujie Town, Nanshan Town and Chengbei Town. The results can provide theoretical basis for improving the utilization rate of chemical fertilizer, fine management of cultivated land and ecological environment in this region, which can help in decision-making of precision fertilization.

“…Selanjutnya Hartono et al (2015) menyatakan bahwa kadar Fe dan Al baik yang terekstrak dithionit-citrate-bicarbonate (DCB) maupun ammonium oksalat serta Al o +1/2Fe o dapat digunakan untuk memprediksi kadar fraksi NaHCO 3 -P i ,-P o , NaOH-P i ,-P o pada tanah sawah di Jawa. P tersedia dan fraksi P tanah sangat dipengaruhi sumber batuan dan tingkat perkembangan bahan induk (Prasetyo dan Setyorini 2008;Augusto et al 2017;Nishigaki et al 2018), sifat fisikokimia tanah (Mehmood et al 2015;Hou 2018;Maharjan et al 2018) dan jenis penggunaan lahan (Prakash et al 2017). Tanah sawah dari endapan aluvial mempunyai komposisi mineral dan sifat kimia yang sangat bervariasi, dipengaruhi oleh jenis bahan endapan yang menjadi bahan induk tanahnya.…”

Akumulasi P tanah sawah di Jawa Barat sudah sangat tinggi dan ini menyebabkan P tersedia yang dapat dimanfaatkan tanaman menjadi sedikit. Bahan induk (aluvium, sedimen dan volkan) berpengaruh terhadap dinamika, proses akumulasi, dan transformasi P di dalam tanah. Penelitian ini bertujuan untuk mengetahui bentuk fraksi P dan membuat model persamaan regresi untuk mengestimasi hubungan fraksi P dengan beberapa sifat kimia tanah. Metode penelitian yang digunakan yaitu survei lapang untuk pengambilan contoh tanah dan analisis tanah di laboratorium. Lokasi penelitian adalah tanah sawah di Jawa Barat. Pengambilan contoh tanah dilakukan secara komposit pada tiga garis transek dari utara ke selatan wilayah Jawa Barat pada 60 lokasi pada lapisan tanah 0-20 cm. Penetapan fraksi P tanah di laboratorium mengikuti prosedur fraksionasi secara sekuensial sesuai metode Tiessen dan Moir yang dimodifikasi. Hasil penelitian menunjukkan bahwa akumulasi P tanah sawah di Jawa Barat didominasi fraksi residual-P, NaOH-Po dan NaOH-Pi. Ketiga fraksi ini paling banyak ditemukan pada kelompok tanah sawah berbahan induk volkanik, kemudian sedimen dan terakhir aluvium. Ada tiga faktor utama yang berpengaruh terhadap distribusi fraksi P, yaitu: 1) Fe dan Al oksida, 2) C-organik dan kadar klei tanah, dan 3) basa-basa dapat ditukar, terutama Cadd. Model persamaan regresi yang cukup baik dalam mengestimasi fraksi P tanah sawah adalah model estimasi untuk fraksi NaOH-Pi dan NaOH-Po dengan nilai R 2 > 0,4 pada taraf p < 0,05.
