“…Thus, in field conditions, sweet potato has problems with Al toxicity before suffering the direct effects of low pH (O'Sullivan et al, 1997). Acid soils with Al saturation greater than 20% seriously limit sweet potato yield (Ila'ava et al, 2000). In these soils, sweet potato responds positively to liming (Camargo et al, 1962;Santos Junior et al, 2020), with increases in storage root yield up to a 60% soil base saturation (Figures 3a, b).…”

Sweet potato (Ipomoea batatas L.) is a versatile crop, but it is often grown in marginal and low-fertility areas, which reflects storage root yields far below its potential. For this reason, balanced liming and fertilization in sweet potato are essential to increase crop yield. Based on this approach, themes related to the nutritional requirements of sweet potato are presented and discussed considering the main cultivars currently used in Brazil as well as references for rational fertilization management in this crop. Sweet potato is a crop that absorbs large amounts of nutrients during its development cycle, but this should not be used as a prerogative to excessively increase the fertilizer rates applied in this root crop. As a strategy for rational fertilization management, one should take advantage of the ability of this crop to associate with N-fixing microorganisms, thus reducing the use of mineral N. Moreover, it is necessary to encourage the use of organic fertilizer, whether using animal manure or green manure. In addition to increasing storage root yield and improving storage root shape, organic fertilizers can partially replace mineral chemical fertilizers. Studies aimed at updating cultivar-specific potassium and phosphate fertilizer recommendations should also be encouraged, as well as research addressing micronutrient supply for sweet potato.

“…It can be inferred from the results that integrated use of lime and inorganic and organic manures not only enhances sweet potato productivity but also increases nutrient-use efficiency (Hartemink 2003). Liming had significant effect on productivity of sweet potato and efficiency of applied chemical fertilizers by countering the acidity and exchangeable aluminium content in the soils (Vele, Pax, and Colin 2000).…”

A field experiment was conducted for five kharif seasons (2006)(2007)(2008)(2009)(2010)(2011) in an Alfisol to study the effect of integrated use of lime, mycorrhiza, and inorganic and organics on soil fertility, yield, and proximate composition of sweet potato. Application of graded doses of nitrogen, phosphorus, and potassium (NPK) significantly increased the mean tuber yield of sweet potato by 44, 106, and 130 percent over control. Green manuring along with 1 / 2 NPK showed greater yield response over that of 1 / 2 NPK. The greatest mean tuber yield was recorded due to integrated application of lime, farmyard manure (FYM), NPK, and MgSO 4 (13.69 t ha −1 ) over the other treatments. Inoculation of mycorrhiza combined with lime, FYM, and NPK showed a significant yield response of 10 percent over FYM + NPK. Conjunctive use of lime, inorganics, and organics not only produces sustainable crop yields but also improve soil fertility, nutrient-use efficiency, and apparent nutrient recovery in comparison to NPK and organic manures.

“…Additionally, its mild alkaline may be suitable for soil amelioration. As a main staple food in many communities (Ila'Ava et al 2000), sweet potato was applied as the model plant. In the test, the sweet potato was planted on the soil ameliorated with MFGDR.…”

We report on treatment and disposal of flue gas desulfurization (FGD) as a solid and hazardous waste. The effects of modified flue gas desulfurization residue (MFGDR) prepared by calcining a mixture of dry/semi-dry FGD residue, potassium feldspar, and/or limestone power on growth of plant and soil amelioration are investigated. The effect of MFGDR on the sweet potato was evaluated by analyzing the soil physiochemical properties and heavy metal speciation in the soil, and the yield, quality, and heavy metal concentrations of the sweet potato. The results indicated that applying MFGDR as soil ameliorant increased total yield by 53.38 %, safety, and the quality of sweet potato. The concentrations of Cd, Cr, Cu, Pb, and As in the sweet potato reduced by 31.34, 70.57, 22.17, 79.49, and 100 %, respectively. The improvements were attributed to enhancement of soil mineral composition contained in MFGDR. The MFGDR could also improve the soil p hy s i c oc h e m i c a l p r o p e r t i e s a n d de c r e a s e d phytoavailability of heavy metals. The application of MFGDR in agriculture not only was a potential and useful technique for recycling and utilization of FGD residue, but also had potential benefits for soil amelioration, plant growth, and decrease of heavy metals in grown products.
