Project-info

Prevention and remediation of soil compaction from agricultural operations

De algemene doelstelling van dit project is om de preventie van bodemverdichting meer onder de aandacht te brengen en tevens de effectiviteit van specifieke remediëringsmaatregelen van verdichting in de diepere bodemlaag te evalueren. Concrete doelstellingen zijn:
Het inventariseren van goede praktijken met betrekking tot teelttechniek en mechanisatie voor preventie en remediatie van bodemverdichting;
Het uittesten en evalueren van meest beloftevolle technieken/maatregelen ter preventieve en remediatie van bodemverdichting door sterk in te zetten op participatie van de doelgroep (landbouwers/loonwerkers/machineconstructeurs en verdelers,…);
Het begroten van een economische balans bij het toepassen van preventieve en remediërende maatregelen om de bewustwording bij landbouwers te verhogen;
Het opstellen van een gids goede praktijken, het uitbreiden en wijder verspreiden van de Terranimo tool en de ontwikkeling van de tool ‘Bodemverdichting in beeld’;
Het verspreiden van de kennis verworven in dit project naar de specifieke doelgroepbedrijven en de ruimere landbouwpopulatie.

Environmental Impact of Soil Structural Degradation by Agricultural Operations

Soil structural degradation from increased agricultural mechanization is not only relevant to farmers, but also for society. We will investigate its consequences on hydraulic properties of different soils, to better predict and spatially explain water transport through structurally degraded soils, and thus better assess its effect and its remediation on agronomy, ecology, environment and society in scenarios of global warming.

Kwantificering van de gevolgen van bodemverdichting en verslemping op de hydraulische eigenschappen van een bodem

De doelstelling van het onderzoek is na te gaan wat de gevolgen zijn van bodemverdichting en bodemverslemping op de hydraulische eigenschappen van verschillende bodemtypes, om het watertransport doorheen een verdichte bodem beter te kunnen voorspellen en ruimtelijk te kunnen verklaren en zo de invloed van bodemverdichting op enerzijds overstromingen en erosie en anderzijds watertekorten bij planten beter te kunnen begroten, ook in scenario’s met klimaatverandering.

Integrated natural resource management for dryland areas - a case of Laikipia East county of Kenya

Conservation agriculture (CA) based on no tillage, use of herbicides, mulch and leucaena as an agroforestry practice and integrated soil fertility management (ISFM) based on drought tolerant varieties and moderate use of NPK fertilizer could be considered as complementary and alternative approaches to the current continuous tillage and nutrient mining farming practices in semi-arid Kenya. Earlier research has concentrated on investigating the effects of either CA or ISFM on soil quality and crop yields. In this project, three paradigms for implementing CA and ISFM to reduce yield gaps under conditions of drought stress are tested on field trials: implementing CA followed by ISFM, ISFM followed by CA, or CA and ISFM simultaneously. Specific attention is given to soil health, water balance, crop growth and economic profitability.

Soil-improving cropping systems for sustainable rice production in the Vietnamese Mekong delta (SUSRICE)

Albeit the increased use of mineral fertilizer and improved cultivars, rice productivity is gradually declining in the Vietnamese Mekong delta. The project aims at increasing crop production by introducing soil-improving cropping systems, while reducing inputs like water and fertilizer, and greenhouse gas emissions. Cropping systems in which rice is rotated with upland crops like maize, soybean and sesame within one year instead of rice monocultures with three rice crops per year, and soil is amended with organic waste materials like compost and rice-husk based biochar will be evaluated on farm. Specific attention is given to soil health, water balance, crop growth, economic profitability and greenhouse gas emissions. Meanwhile, the capacity of Can Tho University staff regarding teaching and research will be enhanced.

Prevention of soil compaction by agricultural operations in Chuquisaca, Bolivia

This project will develop a decision support tool that allows to evaluate the risk of soil compaction due to agricultural operations with heavy machinery. The tool compares mechanical strength of the soil with stresses propagated in soil and exerted by wheels from machinery driving on the soil. It will be used to raise awareness to soil compaction. Meanwhile, the capacity of SFXU staff regarding teaching and research on soil compaction in an
agricultural context will be enhanced.

Effects of soil compaction by agricultural machinery on crop growth and environment

Soil compaction is a major threat to soils worldwide. Field experiments are conducted to understand the interaction between soil compaction, soil-water dynamics, root development and nutrient leaching. Results will be very useful in selecting strategies to prevent and remediate soil compaction. This is crucial from a sustainable intensification perspective, i.e., to intensify agriculture, while minimizing environmental hazards.

Novel pedotransfer function for predicting physical and hydraulic properties of Tanzanian soils

Water relations are among the most important physical phenomena that affect the use of soils for agricultural, ecological, environmental, and engineering purposes. To formulate soil-water relationships, soil physical and hydraulic properties are required as essential inputs. Such data are, however, often not available. This project aims at establishing a new physical and hydraulic properties dataset for soils in Tanzania. Novel data mining techniques that allow to predict those properties from basic soil properties using pedotransfer functions (PTFs) will be developed. Scenario studies will demonstrate how PTFs can improve land management planning.

Assessment of soil quality under conservation agriculture in dryland zones of Malawi

In Southern Africa, especially in semi-arid areas, conservation agriculture (CA) has been introduced since a few years and is highly promoted. Although it may be self-evident to many that CA will improve soil quality and hence increase the resilience of the soils against drought and thus increase yields, this assumption generally goes without rigorous evaluation or detailed testing. Agronomic properties, soil characteristics and economic benefits have not been widely studied among smallholder rainfed farmers. Moreover, the Tropical Soil Biology and Fertility Institute of the International Centre for Tropical Agriculture have recently raised very critical concerns about adoption of CA in smallholder farming systems in Africa. This project aim at critically assess CA for maize production in Central Malawi and Southern Malawi, two districts located in low rainfall zones and prone to drought. Suggestions for improvement of the current CA practices will be made.

Building resilience to drought in Laikipia East District, Kenya: the Conservation Agriculture perspective

The farmers’ concept of drought is an indirect result of land degradation. Crop production suffers because water (and hence nutrients) is not available due to an imbalanced soil hydrology. This project aims at investigating how conservation agriculture can improve the rootzone water balance (by ameliorating soil quality) and hence crop production on farmers’ fields in Kenya.
