Figures & data
Figure 1. Farm sizes and age distribution of the respondents.
Figure 2. Age distribution in the farms and the most common size of farms.
Figure 3. The main types of organic fertilisers used by farmers in the survey.
Figure 4. Amount of applied N presented for intervals of N amounts applied (kg per hectare). The line shows the distribution among respondees (%) for applications of total amounts of N (organic and mineral). The stacked bars show how much of N applied (kg per hectare) came from organic fertilisers, presented as distribution among respondees within each interval on x-axis.
Figure 5. Amount of applied P presented for intervals of P amounts applied (kg per hectare). The line shows the distribution among respondees (%) for applications of total amounts of P (organic and mineral). The stacked bars show how much of P applied (kg per hectare) came from organic fertilisers, presented as distribution among respondees within each interval on x-axis.
