Abstract
Datasets presented here were employed in the main work “Understanding
the heterogeneity of smallholder production systems
in the Andean tropics e The case of Colombian tomato growers”
Gil, et al., 2019. In this region, tomato crop is developed under two
technological levels: low, carried out under open field (OF) conditions
and, a high, by using greenhouses (GH). For OF, data belong
to five municipalities of the Guanent a province (Santander
department), while for GH, data belong to five municipalities of the
Alto Ricaurte province (Boyac a department). The data presented
here includes information on soil parental materials and climate
variables (averages ± standard deviations) relevant from the
agricultural point of view, which were calculated from historical
climate series. Soils natural fertility data, obtained by sampling the
production areas, are also presented. After filtering the data, 67
samples were obtained for OF and 70 for the GH. For GH, a dataset
with the results of 38 soil samples taken inside greenhouses were
paired with the results of samples taken outside these greenhouses
in uncropped areas. In the case of these soil analyses, the
data correspond to tables with the results reported by the laboratory
for both, chemical and physical variables, for each location
in which soil samples were taken. In this work, the main dataset is one that contains the inputs of fertilizers and water, and the corresponding
yields of tomato production cycles managed by local
growers. This information was collected through two data collection
tools: surveys (SVY) to growers about these aspects in their
last production cycle, and through detailed follow-ups of selected
production cycles (FWU). For the OF, we collected data from 71
cycles through the surveys and 22 through the follow-ups, while
for the GH, information from 138 to 38 tomato cycles was collected
through surveys and follow-ups, respectively. A table with the
results aggregated by tomato cycle is attached.
