“…Part of the mechanisms contributing to lower phosphatase activity in non-legume crops could be linked to their low phosphorus demand as exhibited by the low shoot P concentration since these crops do not fix atmospheric nitrogen [45]. Some studies have also shown the comparable capability of non-legumes to secrete acid phosphatase [46] although their levels are lower than those of legumes such as chickpea and cowpea [23]. This could be particularly attributed in part to the phosphorus requirements for symbiotic nitrogen fixation relative to non-legumes that lacks this metabolic function [47].…”

Low available soil phosphorus (P) is associated with its immobility, which renders it unavailable for plant uptake. In addition, farmers normally apply inorganic fertilisers to legumes to activate soil-bound phosphorus using root exudates. Sufficient soil mineral nutrition is key to sustainable crop production, and hence food and nutritional security. The aim of this study was to quantify the acid and alkaline phosphatase activity as an indicator of P supply and availability under varying levels of nitrogen, phosphorus and potassium (NPK) fertilization and different cropping systems. An intercropping (cowpea and amaranth) and fertiliser (control, 25%, 50%, and 100% of the recommended NPK levels) field trial was laid out in a 2 × 4 factorial treatment structure in a completely randomized design (CRD) with four replications. There was higher acid and alkaline phosphatase activity in the rhizosphere of cowpea and amaranth grown as sole crops compared to those from intercropping. The cowpea and amaranth plants grown without fertiliser or 25% NPK had the highest rhizospheric phosphatase activity, while 100% NPK application exhibited the least. The markedly higher phosphatase activity from the low fertiliser application treatments indicates the possible stimulation of microbial activity to supplement P demands for the crops. The study revealed that the application of lower rates inorganic fertilisers in a legume intercrop stimulates the activity of the phosphatase enzymes, which can subsequently liberate soil-bound phosphorus. Plant tissue phosphorus concentration of cowpea and amaranth plants increased proportionately to the increase in fertiliser application up to 50% of the recommended NPK level. The land equivalent ratio (LER) was greater than 1, indicating that it is more beneficial to intercrop cowpea and amaranth as opposed to growing them as sole crops. Overall, the application of NPK fertilizer to amounts of up to 50%, based on the results of this study, appear to be better than 100% in terms of biomass accumulation and phosphate activity.

“…Previous studies have reported that legumes such as chickpea, cowpea, Cyclopia and Aspalathus release more phosphatase enzymes than non-legumes (Liu et al, 2004;Makoi et al, 2010;Maseko and Dakora, 2013). This is because legumes require more phosphorus in the symbiotic nitrogen fixation process than cereals do (Makoi and Ndakidemi, 2008 increase in phosphatase activity in the legume roots and soils leads to a significant increase in plant available P (Makoi et al, 2010).…”

Soil is a fundamental resource and it is crucial to manage its quality in order to enhance agricultural productivity and environmental quality. Soil enzymes catalyze several biochemical reactions which result in the transformation of organic matter, and the release of inorganic nutrients for plant growth and nutrient cycling. Soil enzyme activities are useful biological soil quality indicators since they are operationally practical, very sensitive, integrative, easy to measure and more responsive to soil tillage and structure than other soil variables. There are several enzymes in soil, but those involved in hydrolases and the degradation of main litter components are used most often for evaluating soil quality. This paper reviews the roles of soil enzymes such as β-glucosidase, phosphatase and urease, as well as the implications of their activities for soil quality.

“…Our investigations showed also that phosphatase content was significantly higher in maize soil than soil beneath peanut, which may be due to high density of AMF spores in maize soil and a greater secretion of this enzyme by maize roots. In contrary, Maseko and Dakora (2013) have reported that legumes secrete more phosphatase enzymes than cereal which might be explained by a higher requirement of P by legumes in the symbiotic nitrogen fixation process. The amount of acid phosphatase exuded by plant roots has been shown to differ between crop species and varieties (Kidd et al, 2016).…”

The overuse of chemical fertilizers in agriculture remains an environmental concern, especially in sub-Saharan areas of Africa where soil degradation lead to low crop yield. Crop inoculation with beneficial microorganisms appears a good alternative to reduce chemical substances and improve yield. In this regard, studies on soil biological activities and inoculation experiments on maize (Zea mays L.) and peanut (Arachis hypogaea L.) crops were conducted. The aim of this work was to evaluate the effect of these crops on soil microbial activities and to assess their response to inoculation with two fungi (Glomus aggregatum and Glomus etunicatum) alone or in combination. Rhizospheric and non rhizospheric soils were collected in peanut and maize fields at Takali in northern Côte d'Ivoire. Soil enzymes activities, total microbial biomass, AMF spore and rhizobia densities were determined in these soils. Then, mycorrhizal inoculation experiment of these plant species was conducted in a greenhouse located at Nangui Abrogoua University, Abidjan, Côte d'Ivoire. After three months, plant growth and yield, mycorrhizal and nodulation parameters were measured. Results showed that maize has significantly improved enzymes activities, spore density and total microbial biomass of soil. Effect of peanut was only significant on chitinase. Moreover, soil rhizobia density was reduced under this crop effect. Maize significantly improved these parameters more than peanut. Inoculation results showed a significant enhancement of the height and shoot dry weight of maize with single inoculation with G. aggregatum or G. etunicatum even if a low mycorrhization rate was observed. However, in peanut, the mixed inoculants (G. aggregatum + G. etunicatum) significantly increased the pod weight and nodulation parameters. Results showed the importance of plant cover in the improvement of soil biological quality including enzymes activities and microbial community and suggested that the effect of mycorrhizal inoculation is influenced by many factors as plant species, AMF and soil environment characteristics.
