Assessing Nitrate Leaching in Crop Production through the Application of Crop Simulation Models with Experimental Data from Florida

Lakesh Sharma, Rishabh Gupta, Lincoln Zotarelli, andGerrit Hoogenboom

Lysimeters are often used in research concerning nutrient leachate all over the globe. However, due to factors such as Florida's high water table (a condition when the water level stays relatively close to the soil surface) in some production areas, the assessment and collection of leachate are not feasible. Another obstacle to the use of lysimeters in field research is the fact that several types of irrigation methods are used in Florida (e.g., subirrigation with seepage or drain-tile, overhead, microsprinkler, and drip irrigation) requiring different strategies for leachate assessment. This publication focuses on the use of crop models as alternatives to estimate nitrate leaching from cropping systems at a field scale. This publication's target audience is growers, extension agents, crop consultants, representatives of the fertilizer industry, state and local agencies, students, instructors, researchers, and interested Florida citizens.

Nutrient Management in Low-Chill Peach Orchards: Guidelines for Deficiency Symptoms and Leaf and Soil Sampling

Jonathan Clavijo-Herrera, Ali Sarkhosh, Lincoln Zotarelli, Cheryl Mackowiak, andRao Mylavarapu

Timely and informed fertilization practices in peach production are essential to obtain high yields, optimal fruit quality, and secure long-term orchard health and productivity. Recognizing nutrient deficiency symptoms can help identify which nutrients a plant may be lacking, but a solid nutrient management program should regularly test soil and foliar samples to detect issues before symptoms appear. This publication provides suggested nutrient sufficiency ranges for peach trees, along with practical guidelines for identifying nutrient deficiency symptoms and conducting soil and foliar sampling in the orchard. Its goal is to support county Extension agents and faculty, growers, and homeowners with general and practical guidelines for optimizing nutrient management in peach orchards.

Nutrient Management in Low-Chill Peach Orchards: Guidelines for Fertilizer Rate Application in Florida Subtropical Climate

Jonathan Clavijo-Herrera, Ali Sarkhosh, Lincoln Zotarelli, Cheryl Mackowiak, andRao Mylavarapu

Appropriate fertilization of perennial fruit tree species is critical to ensure vegetative and reproductive growth, as these processes demand considerable amounts of resources. Adequate fertilization management practices at all stages of peach development are essential to obtain high yields and optimal fruit quality, as well as to ensure healthy vegetative growth that supports the crop for the following year. Fertilization practices are also important economically since they represent an important portion of the costs associated with peach production. Improper fertilization can have negative agronomic and environmental consequences. This publication discusses and suggests general fertilization management practices for peach trees growing under the subtropical climate of Florida to provide information to county and state Extension faculty, growers, and homeowners interested in peach production in Florida.

Potato Vine Killing or Desiccation

Lincoln Zotarelli, Steven Sargent, Peter J. Dittmar, andMildred Makani

Proper tuber maturity at harvest is an important factor in producing high quality Florida fresh market potatoes. A mature tuber has improved skin-set, bruise resistance, and storage life. Vine killing not only benefits tuber appearance but can also limit tuber size and improve tuber release from the vine at harvest. Tubers naturally mature as the potato plant senesces. However, improved production methods cause potato vines to remain healthy and green longer into the season. Tuber maturation can be artificially induced by killing the potato vines. The three traditional methods for vine killing are mechanical, chemical, and combinations of the mechanical and chemical methods.
