Increasing food production is a continuous need. In this context, agriculture is a fundamental part of meeting the ever-increasing demand for food. Plant diseases are one of the factors that compromise food production goals, and the characteristics and climate of each production region influence them. Tomatoes are one of the world's most consumed vegetables and are widely affected by various diseases. However, tomato cultivation in greenhouses allows its continuous production. In this context, this research work focuses on the problem of identifying diseases in scenarios of tomato cultivation in greenhouses, where we have specific occurrences of diseases that are affected by regional climatic conditions. Brazil is a major producer of tomatoes, producing more than 3 million tons annually, with 8% of this production being made in the state of Paraná. This study was developed through data collection in collaboration with greenhouse tomato producers from an important region in North Paraná. For this study, we created new datasets with two image sizes: the Tomato Leaf Image Dataset (TLID) with image sizes of 256x256 pixels and 15,256 images, and the Patch Tomato Leaf Image Dataset (PTLID) with patch sizes of 32x32 pixels and 227,218 images. Both datasets comprise seven classes, including four types of diseases, two combinations of diseases on the same leaf, and the healthy leaf. Machine Learning techniques have been widely used to identify plant diseases. This work presents two machine learning methods tested with both datasets. In the proposed models, we combine three convolutional neural networks, a customized CNN, VGG19, and Resnet50, and two voting classification methods using hard and soft decisions. The evaluation performed on the datasets showed that when the patches are used, the results improve significantly, reaching an accuracy of 90.48%. It is also possible to identify the stage of the disease.

Degree of phosphorus saturation (DPS) and soil phosphorus storage capacity (SPSC) have been tested worldwide to predict phosphorus environmental risk in agricultural systems. Our study was carried out in Oxisols from Southern Brazil, to estimate the environmental P-threshold and compare the long-term manured soils with unmanured soils under native vegetation (without anthropic interference) incubated with mineral fertilizer. The long-term manured experiments were conducted under no-tillage with dairy liquid manure (DLM) applied at two sites (sandy clay loam texture, since 2005; and clayey texture, since 2006). Soil samples, from the same type as the long-term manured soils, but under native vegetation were incubated with mineral fertilizer for 30 days. DPS was obtained by P, Fe, and Al extracted with ammonium oxalate and Mehlich-1. P-water and P-CaCl2 were determined to represent the soluble P. Long-term application of DLM affected the environmental P-threshold. The dataset from long-term DLM without incubation resulted in an environmental P-threshold (P Mehlich-1) of 178 mg kg−1 (26% DPS) in the sandy clay loam soil and 77 mg kg−1 (7% DPS) in the clayey soil. Using dataset from soils under native vegetation incubated with mineral fertilizer with liming, the environmental P-threshold (P Mehlich-1) was 75 mg kg−1 (10% DPS) in the sandy clay loam soil and 110 mg kg−1 (13% DPS) in the clayey soil. The distinguished results of environmental P-threshold from the same soil type and texture are a consequence of the soil phosphorus dataset. Datasets constituted by most of values with low DPS or low soil test P (STP Mehlich-1) resulted in low environmental P-threshold, and vice-versa. In general, SPSC was less restrictive than DPS or STP in estimating P environmental risk. It is recommendable to define and follow a protocol to assess P-thresholds creating DPS datasets that provide a high and similar amplitude among different soil types, so the data among places can be compared.
