In West Africa, the uncontrolled use of pesticides by vegetable farmers leads to contamination of soils as well as surface and ground water. Farmers also use various sources of organic amendments which could impact the fate of the pesticides in soils. This study was conducted to identify the type of pesticides and organic amendments used in the main vegetable gardens in Ouagadougou, Ouahigouya and Bobo-Dioulasso three cities of Burkina Faso. Farmers were interviewed individually on their practices regarding organic amendments and pesticides. Sixty one percent (61%) of farmers do not know the instruction regarding the application of pesticides. Fifty three percent (53%) of farmers did never receive training on pesticide application. We found that pyrethroid-based insecticides like lambda-cyhalothrin and delthametrin were the most used by farmers. About 69%, 59% and 100% of the farmers apply the pesticides periodically in their fields respectively in Ouagadougou, Ouahigouya and Bobo-Dioulasso. All the farmers interviewed attested that they do not respect the recommended doses of pesticides. Manure was the organic amendment mostly used in the three cities (41-75%), followed by household garbage (15-41%). In Ouagadougou most of farmers (69%) apply organic amendment at the recommended rate or more while in Bobo-Dioulasso (69%) and in Ouahigouya (57%), the majority apply low rates. There is a correlation between the social status (sex and the education level) and the pesticide and organic amendment management.

“…It was found that the amount of nitrogen in the soil decreases with the aging of the plant growth period, except for the treatment of azotobacter inoculum, as the amount of N increased up to 50 days, and this is due to the azotobacter bacteria in the process of nitrogen fixing process. The phosphorus seems to have an attitude which looks like nitrogen and that has a role of the vaccine isolate Pseudomonas phosphatedissolving and this lead that phosphorus seemed to be transformed from the fixed or total part into a soluble one due to the activity of the solvent bacteria [5,6]. It was found that the use of modern fertilizer technologies to reduce pollution problems and interest in bio-agriculture technology in which beneficial microorganisms are used in order to improve production, and the phosphorus-dissolving bacteria P. fluorescence achieved the highest percentage of available phosphorus in the soil, the highest percentage of humic acid production, and the highest percentage of microbial density [7,8] and a clear diversity occurs between the isolates in the rate of phosphorus free process , due to the variation in enzymatic activity, its production of organic acids, and its ability to dissolve phosphate compounds both quantitatively and type , and that the difference in the density of microorganisms may directly related to what the soil environment provides of nutritional sources or due to the competition that can obtain nutrients, and the strongest microorganisms prevail through their ability to use the available food in their environment , and their ability to optimally adapt to the factors determining their growth in the environment [9].…”

The pots experiment was carried out in green house which belong to the Department of horti culture and Engineering,College of Agriculture, University of Anbar, to study the effect of locally prepared biofertilizers and their enzymatic activity on the growth of maize (Al Maha gender) and the activity of phosphatase, protease, glucosidase, urease, respiratory efficiency, and survival of nitrogen-fixing and phosphate-dissolving bacteria in the soil and some Morphological and physiological characteristics of corn plant, during the spring agricultural season of 2022. The experiment included testing 5 isolates with doubled combinations of isolates: Azotobacter chroococcum, Bacillus megaterium, Azosprillum lipoferum, Pseudomonas putida, Actinomycetes.There were 16 treatments with control treatment (without addition). The treatment A. chroococcum + Az. lipoferum has the highest content of total nitrogen in the soil and in the presence of maize after 60 days reach to 185 mg N kg−1 followed by Az lipoferum treatment at a rate of 177 mg N kg−1, while the lowest nitrogen content in the control treatment was 65 mg N kg−1, and the B. megaterium + P. putida treatment excelled with the highest phosphorus content of 13.65 mg P kg−1, it was found that the bacterial number in the soil reach the highest level in the treatment of B.megaterium + P. putida with the highest level of cfu g−1 soil reach to 3.3*10 7 of cfu g−1 soi.

“…Some research showed that the use of Chlorpyriphos-ethyl leads to a decrease in dehydrogenase activity (Tejada, Gomez, & DelToro, 2011). In addition, Naré et al (2014) showed a decrease in the dehydrogenase activity after application of pesticides such as Endosulfan, Deltamethrin and Profenofos. According to the same authors, this decrease in the dehydrogenase activity is accompanied by the decrease of the microbial biomass and soil respiratory activity.…”

Sesame cultivation is strategic for the economy of Burkina Faso. Indeed, after cotton, sesame is the second most important agricultural product for exportation. However, its production is limited by plant diseases and pest attacks. Facing this situation, large amounts of pesticides are used to boost productivity. But, these chemicals have a negative impact on soil fertility. In this instance, the effects of Supraxone and Lambda-super in the presence of compost on soil microbial activity under rainfed sesame cultivation in a peasant environment were studied. The experiment design was a block of Fisher (BCR) comparing the non-treated parcel (TNT) to the parcel amended only with compost (C) and to the parcel amended with compost and treated with the pesticides (C + P), respectively. Soil samples were taken at depths of 0 -20 cm before sowing at 41st and 81st days after sowing. Respiratory activity and soil microbial biomass were monitored respectively by respirometric tests and by the fumigation-incubation method. The results show that the addition of compost into the soil with or without supraxone treatment and Lambda-super resulted in an increase in microbial biomass and soil respiratory quotient. These results show that the provision of compost in sufficient quantity corrects the inhibitory effect of soil biological activity by pesticides.
