“…The procedure has to be adjusted to physical and chemical characteristics of the soil. The impediments regarding boron leaching are a lower rate of removal in comparison to salt, possible migration in deeper soil layers and consequential contamination of the root zone, the risks of leaching other nutrients, and the risk of boron regeneration from natural reserves [76,172,173]. The relationships between boron and other elements, such as Ca, S, Zn, Si, and Al were used for developing amendments that are intended either for soil improvements or for the alleviation of the toxic effects on plants [174][175][176].…”

Boron is an essential plant micronutrient taken up via the roots mostly in the form of boric acid. Its important role in plant metabolism involves the stabilization of molecules with cis-diol groups. The element is involved in the cell wall and membrane structure and functioning; therefore, it participates in numerous ion, metabolite, and hormone transport reactions. Boron has an extremely narrow range between deficiency and toxicity, and inadequate boron supply exhibits a detrimental effect on the yield of agricultural plants. The deficiency problem can be solved by fertilization, whereas soil boron toxicity can be ameliorated using various procedures; however, these approaches are costly and time-consuming, and they often show temporary effects. Plant species, as well as the genotypes within the species, dramatically differ in terms of boron requirements; thus, the available soil boron which is deficient for one crop may exhibit toxic effects on another. The widely documented intraspecies genetic variability regarding boron utilization efficiency and toxicity tolerance, together with the knowledge of the physiology and genetics of boron, should result in the development of efficient and tolerant varieties that may represent a long-term sustainable solution for the problem of inadequate or excess boron supply.

“…However, this study brings new information indicating that the risk is almost non‐existent in clayey soils with the application of up to 6 kg ha −1 of B. This can be explained by the higher organic matter content in clayey soils, which can store and gradually release B into the soil solution, thus avoiding toxicity (Dhassi et al., 2019; Schmidt et al., 2021; Yermiyahu et al., 2001). Boron toxicity in crops occurs because its absorption is passive, via mass flow, and once absorbed, it has low mobility, easily accumulating in plant tissues, leading to a narrow range of sufficiency and toxicity for crops (Kohli et al., 2023).…”

“…Boron (B) deficiency occurs in various regions of the world and more than 132 crops, and parent material and soil texture are determining factors for B deficiency, which is more common in sandy soils (Shorrocks, 1997). Boron predominant form in the soil is boric acid (BA) (H 3 BO 3 ), which is easily leached by rainfall due to its high solubility (Landi et al., 2019), especially in soils with low organic matter (Dhassi et al., 2019; Yermiyahu et al., 2001), common in tropical climates (Cordeiro, Rodrigues, et al., 2022).…”

Cotton (Gossypium hirsutum L.) is responsive to boron (B) fertilization when there is low soil availability, but the best source and rate to be used and whether this response is dependent on soil texture are still unknown. This study aimed to adjust boron fertilization for cotton as a function of the production environment and B source used. Two field experiments were conducted in the 2020/2021 season in Chapadão do Sul, MS (clayey soil—adequate B content) and Dracena, SP (sandy soil—low B content), Brazil. Treatments consisted of B sources (ulexite [low solubility], borax pentahydrate [BP] [intermediate solubility], and boric acid [BA] [high solubility]), and B rates (0, 1, 2, 4, and 6 kg ha−1) applied to the soil at 25 days after plant emergence. In sandy soil with low B content, application of 2 (high and medium solubility sources) and 4 kg B ha−1 (low solubility source) improved fiber yield between 10% (210 kg ha−1 fiber) and 28% (555 kg ha−1), respectively, as well as micronaire index, strength, elongation, uniformity, and short fibers. Application of B greater than 4 kg ha−1 via soluble sources reduced (between 9% (175 kg ha−1)—BP and 14% (257 kg ha−1)—BA) fiber yield only in sandy soil. When B content in the soil is adequate, B fertilization did not improve yield, but increased fiber strength (4%—1.1 g tex−1) and reduced the short fiber index (16%) by applying 1 kg B ha−1, regardless of the source used. The highest fiber yields were obtained with leaf B contents between 12 and 17 mg kg−1 (sandy soil) and 25 and 27 mg kg−1 (clayey soil). We recommend applying 2 kg B ha−1 (solubility sources) and 4 kg B ha−1 (low solubility source) in sandy soils with low B content to improve yield and fiber quality, and 1 kg B ha−1 in clayey soil with adequate B content to improve fiber quality and replace B amounts removed through harvesting.

“…Ketersediaan boron di dalam tanah dipengaruhi oleh beberapa faktor termasuk pH tanah, kelembaban, kandungan liat, kandungan bahan organik, tekstur tanah, dan keberadaan unsur lain seperti Ca (Dhassi et al, 2019;Havlin et al, 2017). Adsorpsi boron oleh tanah meningkat seiring dengan meningkatnya pH tanah sampai pH 9 dan menurun pada kisaran pH 10 sampai 11.5 (de Sá dan Ernani, 2016).…”

Salah satu gejala defisiensi hara mikro yang kerap muncul pada tanaman kelapa sawit adalah gejala defisiensi hara boron. Boron merupakan unsur hara mikro yang memiliki fungsi vital bagi tanaman diantaranya berperan dalam perkembangan sel baru pada jaringan merismatik, translokasi gula, pati, transport air dan hara, serta berperan penting dalam metabolisme asam fenolik yang sangat penting untuk pertumbuhan serbuk sari yang berpengaruh terhadap pembentukan buah. Pada tanaman kelapa sawit, boron sangat berperan penting pada masa pembungaan dan pembentukan buah. Untuk memenuhi kebutuhan hara boron tanaman kelapa sawit aplikasi pupuk boron dilakukan secara rutin setiap tahun terutama untuk tanaman kelapa sawit muda. Jenis pupuk boron yang umum digunakan di perkebunan kelapa sawit adalah pupuk borax yang memiliki kelarutan yang tinggi. Kelemahan dari pupuk ini adalah hara boron lebih mudah dan cepat hilang tercuci (leaching) terutama pada jenis tanah berpasir dan daerah yang memiliki curah hujan yang tinggi. Sementara itu, di pasaran terdapat berbagai sumber pupuk boron yang diklaim memiliki sifat slow-release sehingga dapat menyediakan hara boron untuk jangka waktu yang relatif lebih lama terutama untuk areal-areal marjinal. Artikel ini menyajikan informasi mengenai unsur hara boron secara keseluruhan termasuk dinamikanya di dalam tanah dan tanaman serta ulasan singkat terkait hasil pengujian beberapa jenis pupuk boron yang jarang digunakan khususnya pada perkebunan kelapa sawit.
