Sunn Hemp—A Promising Cover Crop in Florida

Qingren Wang, Yuncong Li, Waldemar Klassen, and Edward A. Hanlon Jr.

As one of the promising cover crops under tropical, subtropical, or even template climate, sunn hemp (Crotalaria Juncea L.) has shown great advantages in improving soil fertility and increasing the yield and quality for subsequent cash crops. Due to the leguminous feature, sunn hemp can grow well in the soil with poor fertility, grow fast, accumulate a significant amount of nitrogen from soil, suppress weeds and soil root-knot nematodes, and tolerate dry and wet environmental conditions. Therefore, this article aims to elucidate unique features, origin, plant growth, handling, potential benefits, and the limitation in seed production of sunn hemp. It provides basic information to growers, stakeholders, and anyone interested in growing cover crops for crop rotation to optimize the cropping systems for sustainable agriculture.

Cover Crop Benefits for South Florida Commercial Vegetable Producers

Q. Wang, Y. Li, E. A. Hanlon, W. Klassen, T. Olczyk, and I. V. Ezenwa

This document describes the use of major cover crops grown in southern Florida. The intent of this document is to identify promising cover crops adaptable to Florida's climate. Identified cover crops must also contribute to nutrient conservation and improve soil organic matter by incorporation of cover crop biomass. This document also includes discussion of other aspects of cover crop use in the vegetable production systems of south Florida.

Soil pH Management for Optimum Commercial Fruit Production in Florida

Guodong Liu, Rao Mylavarapu, Ed Hanlon, and Wei Chieh Lee

Soil pH is one of the most important soil chemical properties and affects nutrient bioavailability and microbial activity. The purpose of this article is to provide an overview for faculty, crop consultants, crop advisors, fruit growers, and students who are interested in fruit production. The crop response to soil pH varies due to crop genetic diversity. Soil pH determines nutrient bioavailability and hence fruit growth, yield, and quality.
