Manual on soil management and deficit irrigation for Quinoa

Quinoa is one of the most important crops cultivated in the Andean region. However, there is not a lot of information available dealing with soil management or soil and water conservation strategies for Quinoa cultivation. Soil management is an important factor for sustainable agricultural cultivation. A proper management of the soil is important moreover because quinoa is generally cultivated in conditions of low input of fertilizer and water, which reduces the ability to express the efficient use of water and fertilizer characterizing for this crop. A manual was developed in order to cover partly the mentioned needs for the management and conservation of soil and water.

The manual gives a general overview of the importance of soil and its functions, informs about the problems of soil degradation and water problems in current and future situations, gives information on the nutrient management for quinoa cultivation and suggest soil conservation techniques in order to reduce soil erosion. The manual also explains the interaction between water and fertilizer management in Quinoa, under reduced water availability, using the AquaCrop model (FAO 2005). The manual gives the user the possibility to model the crop development of quinoa under different strategies of water and fertilizer application.

The manual covers following subjects:

  • General information of soil functions
  • Climatology of the Altiplano and water management strategies for quinoa production
  • Biophysical factors that determine the production of quinoa
  • Soil fertility management in quinoa production
  • Calibration of quinoa AquaCrop model
  • Factors that influence soil degradation in quinoa cultivation
  • Soil conservation techniques for quinoa cultivation
