Tillage systems in the tropics: management options and sustainability implications. [R Lal; Food and Agriculture Organization of the United Nations.] -- The objectives of this Bulletin are to collate up-to-date information on soil tillage requirements for soils in the tropics; to assess the impacts of different ways of tillage on soil, environment.

This book is intended primarily for agricultural specialists and extension workers in the tropics and subtropics. Part I deals with the objectives, principles and problems of soil tillage in different climatic zones while Part II examines the main implements and systems from the point of view of their purpose, limitations, method of operation and technical data, such as linkage and drive Cited by: 9.

No-tillage cropping systems and concepts have evolved rapidly since the early s and are attracting attention worldwide. The rapid growth and interest is associated with increasing pressures for food production from a fixed land resource base with degrading effects of erosion, soil compaction and other factors becoming more noticeable.

The technological evolution and the expansion of Zero Tillage (ZT) in Brazil has been farmer-led. Its growth has been phenomenal, as shown in Figure 1.

It will be noted from the graph that the tropical Cerrado region lagged behind the initial development in South Brazil by about 10 years. what is tillage is the process of loosening the topmost soil before planting commences in other to expose the soil nutrients to the reach of plant roots 5.

Tillage Practices Land tillage is the operation that follows after the land area has been cleared, stumped and e involves the opening up of. No-tillage (NT) is a major component of conservation agricultural systems. Challenges that have arisen with the adoption of NT include soil compaction, weed management, and stratification of organic matter and nutrients.

As an attempt to overcome these challenges, occasional tillage (OT) has been used as a soil management practice in NT systems. GIZ () Soil Tillage in the Tropics and Subtropics pdf GIZ () Soil Tillage in the Tropics and Subtropics pdf GIZ () Soil Tillage in the Tropics and Subtropics pdf.

Case studies of farmers from across the country provide inspiring examples of how soil—and whole [ ]. Tillage practices There are a large number of more or less well defined tillage systems for soil preparation and crop establishment.

A common approach is to group these according to whether or not they involve ploughing, giving two main groups; ploughed and ploughless tillage. Ronald F. Follett, in Nitrogen in the Environment: Sources, Problems and Management, Conservation tillage.

Use of conservation or reduced tillage (including no-till) continues to increase as an alternative for nearly all forms of crop production. Management systems which maintain crop residues at or near the soil surface have several attractive features, including less on-farm fuel.

Tillage Systems Descriptions. There are a variety of tillage systems available for crop production. While tillage operations are performed for various reasons, producers must evaluate the need for each and every field operation conducted in order to improve profitability.

In addition, the effects of the tillage operations on the soil system and. N.K. Fageria, A. Moreira, in Advances in Agronomy, 11 Root Growth in Conservation Tillage Systems. Conservation tillage is defined as any tillage sequence, the object of which is to minimize or reduce loss of soil and water; operationally, a tillage or tillage and planting combination that leaves a 30% or greater cover of crop residue on the surface (Soil Science Society of America, ).

and Australia, studies conducted in semi-arid regions of Africa appear to support the use of conventional tillage systems.

Some of the reasons for this apparent discrepancy are because of the physical properties of the soils in semi-arid Africa.

CONSERVATION TILLAGE SYSTEMS. Conservation tillage systems (described below) can be an important part of a sustainable agricultural system, in that they can be used to decrease soil erosion losses ordinarily associated with typical US agricultural practices.

It is important to remember that anything that is done to decrease erosion losses also decreases the need to add as much fertilizer. ). The conservation tillage practices, developed mainly for large scale mechanized agriculture need to be adopted for rainfed pulses in India (Kumar et al., ), which are systems of managing crop residue on the soil surface with minimum or no tillage.

systems in Brazil’s tropical zones. Vast areas of forest have been cleared in the tropical areas of Brazil for establishment of pastures that become unproductive once the native fertility of the soil is exhausted; this leads to yet more forest clearing.

The minimum tillage systems can be grouped into the following categories, 1. Row zone tillage Primary tillage is done with mould board plough in the entire area of the secondary field; tillage operations like discing and harrowing are reduced and done only in row zone.

Plough plant tillage. In a 4-wheel tractor system, three-disc, seven-disc and offset ploughs are the most common. Tined plows are preferable in the upland systems but as yet not widely available in Asia.

primary tillage 2. Secondary tillage Secondary tillage is any working completed after primary tillage and is undertaken for. reducing clod size, weed control. Tillage is the manipulation of the soil into a desired condition by mechanical means; tools are employed to achieve some desired effect (such as pulverization, cutting, or movement).

Soil is tilled to change its structure, to kill weeds, and to manage crop residues. Soil-structure modification. Rudimentary Sedentary Tillage. This is a subsistence type of agriculture and it differs from the aforementioned types because the same plot of land is cultivated continuously year after year.

Fallowing of land is commonly adopted to maintain soil fertility, and is a technique often adopted in tropical regions. Experimental data on tillage requirement of cocoyam (Xanthosoma sagittifolium) are needed to identify the most suitable tillage methods for managing the fragile Alfisols of the humid tropics to ensure sustainedfive tillage methods were compared as to their effects on soil physical and chemical properties, and growth and yield of cocoyam on an Alfisol at Owo in the forest.

The term “soil management” refers to the human manipulation of chemical, physical, and biological conditions of the soil for the production of agricultural plants. Good soil management helps maintain and improve soil fertility while sustaining optimum crop yield over time, whereas inappropriate soil management practices can lead to the degradation of soil fertility and a declining crop.

This book presents the problems of traditional tillage systems and the results of tests carried out on appropriate conservation tillage implements and systems for smallholder farmers in semi arid.

A model study showed that feed limitation, which is common in tropical farming systems with livestock, implies that maximum herd output is achieved with small herd sizes, leaving low-quality feeds unutilised.

Maximal herd output is not achieved at maximal individual animal output.Pasture/crop rotations, such as the tropical ley system (McCown et al., ) are one example of biologically-based systems. Dalal et al. () Jones et al. () and Cogle et al. (, a) have discussed the advantages and disadvan- tages of pasture/crop rotations in tropical .This book, No-tillage Seeding in Conservation Agriculture, provides a broader picture of the equipment used in conservation agriculture cropping systems.

It includes chapters on material not previously covered, for example, the management of crop residues and cover crops, preparation for the no-tillage seeding operation, and controlled-traffic.
