Abstract
The objective of this paper is to contribute to the implementation of less-impacting farming practices in environmentally sensitive areas. Vila Velha State Park is located in Campos Gerais, a region of high-technology agriculture. Typical farming systems in the park’s buffer zone were identified in visits, and characterized in consultations with experts, agronomists, retailers and stakeholders. Three major systems (A, B and C) were described, considering the most common practices in crop rotation, choice of products and machinery operations for soybean and corn production. Systems A and B are characterized by high investment and technology level, though System A has more capital for investment. System C is typified by the use of service packages offered by commissioned retailers. Alternatives to mitigate environmental impact could potentially arise in experiments conducted in association with Farmers A and B, and through economic studies with Farmer C
Highlights
Vila Velha is a set of wind-sculpted sandstone formations of significant scientific, cultural and ecological value, located in Southern Brazil (25°15' S, 50°00' W), state of Paraná, in the region called Campos Gerais (“General Grasslands”)
This paper focused on regional corn and soybean production systems
The selection of seeds, pesticides and fertilizers used in all steps of corn production in the buffer zone of Vila Velha State Park (VVSP) (Systems A, B and C) is displayed on Table 1
Summary
Vila Velha is a set of wind-sculpted sandstone formations of significant scientific, cultural and ecological value, located in Southern Brazil (25°15' S, 50°00' W), state of Paraná, in the region called Campos Gerais (“General Grasslands”). The 3,270hectare Vila Velha State Park (VVSP) was created in 1953, with the objective of preserving a valuable site of natural heritage. Conservation units such as VVSP require a delimited buffer zone, where human activities are subject to specific norms and restrictions with the purpose of minimizing negative impacts (Strey, 2003). Typical summer crop rotations in Campos Gerais are 1/3 corn (Zea mays L.) and 2/3 soybeans (Glycine max (L.) Merrill); winter rotations consist of 1/3 wheat (Triticum aestivum L.) and 2/3 bristle oat (Avena strigosa S.). The utilization of crop rotation is imperative, considering characteristics of soil and climate
