“…In addition, conservation tillage can promote good soil structure to better store nutrients. Similarly, strong water retention and aeration improve soil's physical properties and can provide a good environment for crop growth [36,37]. The results of this study also show that the L treatment improved soil's physical properties (Table 4).…”

Ridge tillage at two fertilizer depths is a new type of conservation tillage method that was previously shown to substantially improve rice yield. This study aimed to compare the effects of continuous ridge tillage at two fertilizer depths (L treatment) with those of conventional cultivation (P treatment) on bacterial and fungal diversity in the rice root zone and study the correlation between microorganisms and yield components. At the mature stage, the yield and yield components of rice plants were compared. Test soil (0–20 cm) with continuous tillage for 3 years was used for high-throughput sequencing to analyze the microbial community structure in the root–soil of the two treatments. We found that the L treatment increased soil nutrient content and improved soil physical properties, which altered the composition of the microbial community. The bacterial ACE and Chao indices in the L treatment increased by 1.46% and 1.83%, respectively, and the fungal ACE and Chao indices increased by 5.25% and 5.49%, compared with the P treatment, respectively. The average theoretical yield under the L treatment was 9781.51 kg/ha, which was 19.23% higher than that under the P treatment. Continuous ridge tillage at two fertilizer depths can provide a better soil environment for rice growth and increase the yield.

“…In Mozambique, the average maize yield is less than 1.5 t ha −1 of the estimated potential of 5 t ha −1 [18] on fields smaller than 2 ha [15,19], thus emphasizing a considerable yield gap. Here, research about the effect of the tillage system, fertilization, and cropping pattern alone on maize and legume stover and grain yield [3,20] and soil physical properties [21] have been conducted. However, there is a paucity of information concerning the combined effects of tillage system, fertilization, and cropping pattern on soil chemical properties, maize and legume stover and grain yield, as well as competition indices of intercropping systems.…”

Sub-Saharan Africa (SSA) agriculture is characterized by dependence on erratic rainfall, inadequate conservation practices, and a decline in soil fertility resulting in low crop productivity. Therefore, conservation agriculture (CA) has been proposed as an alternative to improve soil fertility and productivity. Hence the aim was to investigate the effects of tillage systems, fertilization, and cropping patterns on selected soil chemical properties (pH, organic carbon, total nitrogen, extractable phosphorus, exchangeable cations, and cation exchange capacity) and identify which cropping pattern maximizes stover and grain maize–legume productivity and land use. A two-year (2016/17–2017/18) field experiment in a loamy sand soil was conducted at Nhacoongo Research Station, southern Mozambique. Two tillage systems (conservation (CA) and conventional tillage (CT)), two fertilization treatments (fertilized and unfertilized), and seven cropping patterns (four sole crops and three maize–legume intercrops) were evaluated in a randomized complete block design with split–split plot arrangement and replicated four times. CA practices resulted in significantly higher soil chemical properties and increased stover and grain yields as compared to CT practices, but fertilization demonstrated insignificant effects on soil chemical properties and significant influences on stover and grain yield of maize and legumes. Cropping patterns induced no significant effect on soil chemical properties and either stover or grain yield. Estimated indices like land equivalent ratio (1.18–2.67) and competitive ratio index (0.01–1.72) confirmed the advantage of intercropping against sole cropping. This is largely supported by the estimated values of aggressivity and relative crowding coefficient. Smallholder farmers can therefore benefit by adopting CA.

“…Another factor that affect soil fertility is agricultural practices, namely excessive soil tillage with no soil cover [18]. Conventional tillage provokes the degradation of the soil, with consequent fertility depletion, mainly through the decomposition of organic matter, with disruption of the soil structure and decrease of the aggregate stability [18]. Moreover, soil erosion provoked by the wind and rainwater is a direct consequence of unsustainable conventional tillage practices.…”

Mozambique is one of the poorest countries of the world. However, it has natural resources and if they are managed under sustainable development principles, Mozambique can overcome the current problems. In the present socio-economic status, soil is one of its most important resources and must be protected from pollution and from degradation. This review focuses on the identification and discussion of the main soil quality stressors, namely: soil fertility; deforestation and its sources: agriculture, timber harvesting, charcoal production and uncontrolled fires; mining activities, manly gold artisanal explorations and industrial open-pit coal mining. The sustainable use of the natural resources is mandatory to allow future generations to continue profiting for this nature-based wealth.
