Introduction
In this blog, we will explore the concept of agriculture by processes, a technology pioneered by Ernst Götsch. But first, let us understand what the word "process" means. Derived from the Latin word "procedere," which means "to proceed" or "to go forward," a process can be seen as a path or a way forward. In the context of agriculture, it refers to the methods and systems employed to recreate the abundance and ecological processes of natural forests in our own agricultural practices.
Agriculture by processes aims to enhance and accelerate ecological processes. For instance, in a degraded pasture, where the soil has been left bare for over a decade, natural processes occur at the pace of nature. However, to achieve faster and more efficient results, intervention is required. The first step in this process is to clear the existing grasses, creating space for new growth.
After clearing the grasses, tree pruning becomes essential. Pruning certain tree species, like the pequi tree, stimulates vigorous regrowth. Understanding the characteristics of different tree species is crucial to determine how they respond to pruning. By utilizing this knowledge, the agriculture by processes approach ensures optimal growth and development.
Establishing a New Ecosystem
Once the initial steps of clearing and pruning are complete, the next phase involves creating a new ecosystem through planting. This may begin with horticulture and gradually transition into establishing a forest. In this process, various plant species are carefully selected and introduced to the ecosystem. For example, in a degraded pasture, herbs like thyme and parsley are planted, followed by trees such as pitanga and araçá.
Key to this process is the use of inputs like rock powder and chicken manure to nourish the soil. These inputs, along with the right selection of plant species, contribute to the establishment of a thriving ecosystem. However, the goal is to minimize external inputs and allow nature to take over, creating a self-sustaining system.
Revolutionizing Conventional Agriculture
Agriculture by processes is revolutionizing conventional agriculture practices. Researchers like Professor Celso Tomita, Professor Eline Ingan, Professor Cristine Jones, and Professor T are at the forefront of this movement. They have developed innovative techniques and technologies to accelerate ecological processes and establish a strong microbial presence. These include the use of fermented solutions and effective microorganisms.
While large-scale machinery for processing trees and working in arboreal environments is still under development, advancements in this area are promising. Once the technology aligns with the principles of agricultural processes, the need for annual microbial inoculation may be eliminated. This is a significant shift from current practices, where microorganisms need to be reintroduced each year.
The Importance of Continuous Processes
One of the core principles of agriculture by processes is the ongoing nature of the process itself. It is not a one-time fertilization program but a continuous cycle of growth and regeneration. Interruptions to this process can be detrimental to the ecosystem. For instance, in large-scale agriculture, frequent disruption due to the use of chemicals like glyphosate inhibits the natural processes of life in the soil.
By maintaining a continuous process, the soil improves over time, leading to higher organic matter content and increased nutrient availability. This continuous improvement creates conditions for the development of Terra Preta, a nutrient-rich black soil that is highly desirable for agriculture.
Case Study: Advancements in the Field
Let us now examine a real-life example of how agriculture by processes can transform a degraded area into a thriving ecosystem. Starting with horticulture, the initial stage involves planting herbs and vegetables. Over time, more diverse plant species, including trees, are introduced to the system. Through careful management and a focus on nurturing the ecosystem, the soil quality and nutrient availability improve.
In this case study, after five years of implementing agriculture by processes techniques, the ecosystem has matured significantly. The increased biomass and diversity of plant species have created a self-sustaining system that requires minimal external inputs. Nutrient availability has improved, and the soil organic matter content has doubled.
Key to maintaining the continuous process is the strategic selection of plant species and the careful management of the ecosystem. By avoiding disruptions and minimizing reliance on external inputs, the system becomes increasingly self-sufficient. The ultimate goal is to recreate a paradise within our agricultural landscapes, where nature thrives and productivity is maximized.
