Crop Yields and Soil Phosphorus Lability under Soluble and Humic‐Complexed Phosphate Fertilizers

Abstract: Phosphorus is one of the most limiting nutrients for plants in weathered tropical soils. To overcome this constraint, the use of humic‐complexed phosphate fertilizer may be considered as one alternative, which would reduce P fixation and increase its bioavailability. This study aimed to determine the crop yield response and soil P lability changes after five crop cycles under humic‐complexed and non‐humic‐complexed superphosphate cumulative applications. The field experiment was conducted for 4 yr (2010–2013) … Show more

“…However, there is no consensus on whether this mechanism -attributed to the organic fraction of the organomineral fertilizer-is effective or not in increasing the efficiency of nutrient use of the mineral fraction of such mixed fertilizer, as in some cases, there is no increase in fertilizer efficiency (Chagas, Guelfi, Emrich, Silva, & Faquin, 2016;Chien et al, 2014;Frazão et al, 2019). Conversely, there are small increases in fertilizer efficiency in other cases (Herrera et al, 2016;Hopkins, Fernelius, Hansen, & Eggett, 2018). When compared with the response of mineral fertilizers, the crop response to organomineral fertilizers is quite variable; according to the literature, there are gains (Deeks et al, 2013;Frazão et al, 2019), losses (Antille et al, 2017;Frazão et al, 2019), or equivalent efficiency (Corrêa et al, 2018).…”

“…However, the type of fertilizer may alter the initial development of the plants, since organic fertilizers need to be mineralized for the release of nutrients (Antille et al, 2014b). Regarding cultivated species, among them wheat (Triticum aestivum), the nutrient supply is predominantly done in the form of mineral fertilization, which stands out for the high concentration and solubility (Herrera et al, 2016).…”

“…Hence, application of chemical fertilizer-P may be used efficiently to overcome yield gaps. But the application of fertilizer-P demands high cost as most of the P makes a complex with calcium (Ca), aluminum (Al), and iron (Fe) which make it unavailable for plant uptake (Herrera et al 2016). In undisturbed natural soil, a considerable amount of P (400-1200 mg kg −1 ) is present (Rodríguez and Fraga 1999).…”
