“…Mean, standard deviation, coefficient of variation (CV) and Student's t-test of the relationships between leaf tissue nutrient contents in high-yielding U. brizantha pastures in the rainy and dry seasons in northern Espírito Santo State, Brazil.Satisfactory results from DRIS have been reported for different crops, e.g., pine(Sanchéz-Parada et al, 2018), rubber(Chacón-Pardo et al, 2018), sugarcane…”

“…DRIS standards have been successfully used to interpret leaf analysis results in different annual and perennial crops, such as pine (Sanchéz-Parada, López-López, Gómez-Guerrero, & Pérez-Suàrez, 2018); rubber (Chacón-Pardo, Camacho-Tamayo, & Bernal, 2018); sugarcane (Mccray, Ji, Powell, Montes, & Perdomo, 2010;Santos, Donha, Araújo, Lavres Júnior, & Camacho, 2013); common bean (Partelli et al, 2014), potato (Queiroz, Luz, Oliveira, & Figueiredo, 2014), rice (Wadt et al, 2013), cotton (Serra et al, 2013;Kurihara, Venegas, Neves, Novais, & Staut, 2013), guava (Souza, Rozane, Amorim, & Natale, 2013), mango (Politi et al, 2013), orange (Dias et al, 2013), apple (Xu, Zhang, Wu, & Wang, 2015), and grape (Teixeira, Tecchio, Moura, Terra, & Pires, 2015). However, no studies on U. brizantha pastures and their nutritional diagnoses based on DRIS norms are available.…”

To diagnose and monitor the nutritional status of commercial crops, reference standards must be established based on chemical analyses of soils and leaf tissues. Therefore, the objective of this study was to establish sufficiency ranges, DRIS standards and leaf nutritional diagnoses for palisade grass pastures in the rainy and dry seasons. Of a total of 105 sampled pastures, the 20 highest-yielding areas were used to establish reference standards. In the other, low-productivity pastures, the nutritional status was diagnosed in both the rainy and dry seasons for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), boron (B), copper (Cu), iron (Fe), nickel (Ni), molybdenum (Mo), and zinc (Zn). A productivity of 15 tons ha-1 year-1 was determined as the threshold to separate high-yielding (> 15 tons ha-1 year-1) pastures from low-productivity pastures (< 15 tons ha-1 year-1). Sufficiency ranges and foliar DRIS standards were established for palisade grass pastures in the rainy and dry seasons, which resulted in the recommendation of region- and season-specific sufficiency ranges and DRIS leaf standards. In the rainy season, in more than 50% of the evaluated pastures, nutritional deficiencies in all nutrients except K, B and Zn were observed, while in the dry season, only N, P, Cu, and Mn were deficient.

“…As most fruits, especially cupussu, are rich in potassium (K) and their productivity depends on the contents of this nutrient in the soil, their replenishment becomes necessary to maintain the cupuassu productivity [1,9,10]. Large amounts of organic residues from cupuassu pulping processing are currently found available piled up near the dwellings and/or agroindustries in the municipality of Presidente Figueiredo.…”

The cupuassu (Theobroma grandiflorum (Willd. Ex Spreng.) K. Schum.) is a native fruit tree which has, in the past years, acquired great social and economic importance for the regional farmers. The nutrient-rich and often wasted cupuassu tree fruit shell residues can contribute to the improvement of the low fertility soil of Amazonia. A trial was carried out on a small holder’s cupuassu plantation in Central Amazonia to ascertain the effect of organic fertilization on the recovery of soil fertility and plant nutrition by using material from cupuassu shell residues and Inga edulis pruning (branches and leaves). The fertilization with cupuassu rinds + Inga prunings improved soil fertility, mainly by the increase of K and Ca in the soil, but only with liming, which appears to favor the mineralization of these nutrients. At the 0–10 cm depth, the Ca level increased about 50% compared to the control and the K level increased 75% compared to the cupuassu shell treatments. The significant increase of about 30% in N absorption by trees in the plots without liming shows that the application of green manure can increase the mineralization of N in Oxisols. These results show that the organic residue sources used can result in a nutrient-bearing organic fertilizer and become a low-cost alternative for recycling cupuassu processing residues.

“…However, for the success of this method, the nutritional standard must be specific for each region (PARTELLI et al, 2007;WADT et al, 2012;, and may vary according to the plant genotype, age, phonological stage and the season of the year (PARTELLI et al, 2007;, GOMES et al, 2016MATOS et al, 2017). DRIS standards were successfully used for various perennial crops, such as peach (AWASTHI et al, 2000), mango (RAJ & RAO, 2006), cupuaçu (DIAS et al, 2011;WADT et al, 2012), guava (SOUZA et al, 2013), orange , apple (XU et al, 2015) and grapes (TEIXEIRA et al, 2015). Yet, no DRIS standard was developed for cocoa.…”

Soil patterns and foliar standards for two cocoa clones in the States of Espírito Santo and Bahia, Brazil

The objective of this research was to establish soil patterns and foliar standards for clonal crops of cocoa CCN51 and PS1319 in the Atlantic regions within the northern Espírito Santo and southern Bahia States. Samples were collected from September to October 2015, in 45 high productive plots, being 23 plots of clone CCN51 and 22 of clone PS1319. Sufficiency ranges for soil and foliar standards were recommended for cocoa clones CCN51 and PS1319 planted in the Northern Espírito Santo and Southern Bahia states. Differences in the contents of foliar macronutrients K, Ca, Mg, S and micronutrients Fe and Mn, were verified between clones CCN51 and PS1319. Differences reported for standards from different geographical regions confirmed that these standards need to be regional and specific for different cocoa clones.
